First edition cover  One does not teach Hinduism. One seeks to bring out the knowledge that is deep inside each one of us. And that is what this book seeks to help you do. Hinduism is the essence of human efforts to answer questions. Why and how did we come to exist? What is our role in the Universe? Our relationships to other living beings and to Nature? How should we live our lives? With 14 chapters and 188 references, this book is written for and by learners like you. We blend what we learned from our parents with what the modern world teaches us. The book is at the level of an introductory college text. It is intended for young people seeking to educate parents and friends, and vice versa. The last 2 chapters discuss the authors’ opinions, and present several basic prayers learned from our parents.

Gallery Of Images

We are keenly aware that an electronic edition does not allow us to include many images because of file download cost, and more because of the difficulty of obtaining copyright permission on images that in some cases trace back several millennia. However, the sheer color and grandeur of Hinduism must be given due space. We ventured to upload several images - with apologies to the copyright owners where we have been unable to identify them.

A Gallery on Sanatana Dharma has been developed to accompany the book.
As explained in the book, Sanatana Dharma is the continuing search and reasoning to find the truth about how and why we came to be what we are. Throughout the ages, humans, and most probably, the beings that preceded Humanity and continue to be all around us, have developed knowledge. We can look at the structure of all this knowledge in a very simple manner as three categories:

Avataras
Bhakti
Purana

The first visual category is Humanity's effort to visualize the Avataras: the appearance, not necessarily in human form, of the ParamAtman, the Supreme Being. Hindus believe that the ParamAtman is centered inside each of us and throughout Creation, but one of our Core Beliefs is that in the most dire times, the Supreme Being will take a visible form, to save and protect those who are righteous and follow the path of Dharma, and to destroy those who threaten to destroy Dharma. Thus humans find it easier to visualize the ParamAtman and these Avataras, or embodied Appearances, in some identifiable forms. The best known Avataras are the Dasa Avataras (Ten Avataras) of Vishnu, the Protector Form of the ParamAtman. However, when people visualize the ParamAtman in other forms, such as Shiva, Ganesha, Devi, these are all properly called Avataras at least for our purposes. Without further Ado, let us look at some images.

As our book explains, in Sanatana Dharma, the concept of "Ardha Nari Iswara" defines the Supreme Being for those of us want to identify gender with the Supreme Being. Man when seen from one aspect, woman from the other. There is no assumed superiority of one over the other: they are indeed one and the same. The Supreme Being is also seen in three forms, known as the Tri Murti. These are Brahma the Creator, Vishnu the Protector (who can also destroy) and Shiva, another form Who can be both Protector and Destroyer. In each case, there is a female form: Sarasvati Devi, with Brahma, associated with knowledge. Lakshmi Devi with Vishnu, associated with wealth and Parvati Devi with Shiva, associated with beauty and the Arts. The female form can also appear in Kali form, another who can both bless and destroy, the ultimate form of Shakti, (the term for Power), the all-encompassing name for the female form of the ParamAtman.

The second category of images is Bhakti. Humans sought ways to express their devotion, love, admiration, and sometimes fear, of the Supreme Entity. They dedicated their lives, and surpassed themselves in excellence, in this pursuit. Bhakti took innumerable forms, as Sri Krishna explains so lucidly in the Bhagavad Gita. Bhakti led to the construction and consecration of temples, ranging from caves to grand edifices reaching into the heavens. Bhakti was expressed in prayer, poetry, drama and song. Bhakti came in outstanding technology and engineering; as well as in the grand imagination that led to art and sculpture. And Bhakti also came in lifetimes of dedicated searches for The Truth, the meaning of Creation, the Right Path. 

The third category is the Purana: the Record of the Ancients, continuing very alive through today and even making predictions for the future. Many of the products of Bhakti became articles of the Purana.

Top Customer Reviews 5.0 out of 5 starsA lucid and precise introduction to Hinduism, also called Sanatana Dharma By S. Kalyanaraman on May 9, 2015 Format: Kindle Edition A tour de force, accomplished with skill and ability. This is a textbook which is sure to become a mandatory reading for all students, teachers and citizens of the world interested in getting an authoritative introduction to Hinduism, a religion practised by over 1.3 billion people all over the world. The authors waste no space on their own credentials. True to their beliefs, they allow the reader to gauge those from their work through reasoning and logic. This book is a thoughtful, lucid and carefully referenced introduction to an infinitely vast and complex subject. It is written in the style of a Upanishad - we are asked to engage in thinking, and 'bring out the knowledge that is deep inside" each of us, even as the authors guide us. It is exactly what it says: an Introduction to Hinduism, but with no compromise on depth. That is where the authors' experience as technical experts and as teachers, become apparent. They want every reader to remain in their own comfort zone, and gradually become confident in their understanding and knowledge. Despite being a book on religion, nothing is presented as dogma, everything is based on scientific and societal reasoning and argument. While high-schoolers will enjoy the informal style, so will the rest of us, as the ideas and explorations scale seamlessly across the aeons, opening doors to the works of the giants, starting with Vyasa and Valmiki, all the way to those leading the intellectual debates in 2015. The references to other belief systems, where appropriate, are confidently knowledgeable and respectful, just as much as on those to the numerous Schools of Thought within Hinduism. However, the explanations of Sanatana Dharma are not based on comparisons to any other religion: Sanatana Dharma stands by itself. The chapters on the Vedas, Puranas, and the Bhagavad Gita contain numerous references to deep philosophy, while those on the Epics are written with the confident comfort of believers with empathy for the human drama and the writers of the Epics. A uniquely comprehensive textbook and source of references, this book is at once deeply traditional as well as ultra-modern. It has the technical facts and details expected of a relevant textbook, without being cluttered with details. It presents the arguments and debates of millennia with just the right amount of human and social context. It presents a final chapter that weaves far-reaching research findings from several different fields into a succint logical argument on fundamental issues, but true to their faith, the authors remind us that these are just their faith-based observations, and leave us free to reason for ourselves. The unique chapter on Vasudhaiva Kutumbakam takes us on an eye-opening whirlwind tour of the vast reaches of Sanatana Dharma, both in ancient times and in the present. The book is designed and formatted with the busy technically-equipped learner and handheld devices in mind. This must be the reason why there are so few pictures, tables and other items that one might expect in a print book. One is expected to browse the Internet, or visit temples, to visualize the places, concepts and events described in the book. Comment 6 people found this helpful. Was this review helpful to you?

 

2. An excellent and intellectually stimulating reference By diskrybe on June 26, 2015 Format: Kindle Edition Verified Purchase This is a meticulously researched and comprehensive work on Hinduism leavened with the personal insights of the authors. Padma and Narayanan Komerath have produced a marvelous resource for contemporary explorers of Hinduism who approach it from diverse levels of knowledge, personal backgrounds and perspectives. The format allows you, the reader, to begin from where you are, and navigate through the chapters in any order you may choose. It is an engaging and thoughtfully presented journey through the vast and ancient river of Sanatana Dharma and its myriad tributaries. Hindus often have to resort to noise-cancelling headphones to shut out snarky academics and lay commentators intent on promoting selective, biased and obtuse perspectives of their faith. Hindus are the only faith community whose members have to deal with the mindset that outsiders have a better grasp and a more authentic interpretation of their beliefs than they themselves do! For clarifications on Islam, you respectfully petition an Islamic scholar. For insights on Hinduism, you consult a white American scholar member of the American Academy of Religions, who has spent a year or two in India and has as much connection with Indian culture as an alien from Mars might have with the social, reflective and emotional inner space of that scholar. Not only that, aspiring Indian scholars must all admire and unquestioningly regurgitate the sage observations of the outsider in order to be perceived as erudite. Like Hemingway’s Old Man of the Sea, this mindset places a chokehold on those seeking to correct misperceptions of Dharma, painting them as dishonest, regressive or deluded apologists. Padma and Narayanan Komerath’s opus is therefore a valuable and necessary addition to the study shelves of serious seekers. It incorporates ancient wisdom without shutting out recent developments in the scientific understanding of reality. Furthermore, it makes no claim to having the last word. The authors state at the very outset they expect and accept dissent. From the introduction: “We note in all humility that many will find much to disagree here, and that is quite all right. It is a sign of human thought process, and the first lesson is that free thought and debate are welcome in Hinduism. It is also essential to our own continued learning. “ May the mutual learning experience begin, and endure as long as thought. Comment 4 people found this helpful. Was this review helpful to you?

3. The most comprehensive and lucid summary of Hinduism that I have ever read. By benne on May 11, 2015 Format: Kindle Edition Dharma is a system of ethics and moral values that even God must abide by. For 5000 years, "Hinduism" which is actually called "Sanatana Dharma" has been preserved and propagated in India by means of narratives and epic stories so that Hindus used to grow up with an instinctive knowledge of Hinduism (or Hindu Dharma). Mobility and the migration of tens of millions of Hindus to places outside India has broken the narrative chain, often leading to a sense of loss as highly educated and otherwise successful Indians are unable to explain the hoary roots of Hinduism and its deeply refreshing values to their children, let alone anyone else. Earlier attempts at explaining this subject have been hampered by a lack of ability of most Indian writers in English to connect up the tens of thousands of bewitching stories from Hindu culture with the 5000 plus year old "eternal sound" of the Vedas. This requires the double skill of being fluent in English as well as being well versed with Hindu dharma - a trick that Narayanan Komerath and Padma Komerath have managed to perform with ease in this book. This is the most comprehensive and lucid summary of Hinduism that I have ever read. I would recommend this book for every Indian and certainly every Hindu who can read English. I believe the book is a particularly valuable contribution for the millions of Hindus living abroad who might, at some time, have felt frustration at their inability to convey the meaning and place of Hinduism today while their children grow up in a modern culture with Twitter-friendly attention spans and an overload of information. Definitely 5 stars, Comment 5 people found this helpful. Was this review helpful to you?

4. An excellent A to Z book on Hinduism - its philosophy and practice BySugrutha R Kamat on June 29, 2015 Format: Kindle Edition First, congratulations to Padma and Narayanan Komerath on their work of passion, love and conviction. At the very first read it is obvious that a lot of heart-felt and soul-felt hard work has gone into its making with much backing of the intellect. The book seems targeted at a wide audience ranging from those that are entirely new to hinduism to those well acquainted as practitioners, and that is no mean feat. Starting with a very thoughtful and helpful glossary to finishing with bibliography with everything about Hinduism - A to Z - in between - Vedas, Vedanta, Avatars, Puranas, Temples, Rituals, Traditions and finally a candid, honest and frank discussion on issues, concerns and confusions surrounding caste, sati, aryan-aravidian divide etc. without denial or self-flagellation, is indeed a monumental manuscript however humbly presented. It will make a splendid college text book. It will also make a ready reckoner, quick reference and an FAQ on all things Hindu. I look forward to gifting it to a lot of people. I was taken aback by some of the definitions that were so simple and succinct and powerful at the same time. Nothing important is left uncovered, but instead of confusing details that often descend into a chaos of contrived and conflicted impressions, everything is left at very rudimentary explanations and left for readers to explore for themselves later. The book is very interesting to read, very extensive, exhaustive and comprehensive (I will even confidently say complete, as complete as Hinduism can be) in coverage, very impressive in brevity and clarity, in short, as good as it can get. Most importantly, although written by believers, the book does not evangelise, it has a very "take it and love it if you can' attitude. Congratulations again, to the authors.

6. Hinduism...a Dharma, after all ByAashrayon June 11, 2015 Format: Kindle Edition We talk about how not to lead the next generation away from Hindu roots. Well here is an absorbing book not only catering to the next but also to the naysayers 'ignorant' in the present generation. Even read as a bedtime story, the book encapsulates the basics as well as the advanced with amazing alacrity. Its a must read especially for those that quite often profess to be knowledgeable yet are shallow at best when they pout their utterance. And for those that moan that Hinduism is just a way of life - hey get it finally folks It is a religion: the sacred Hindu Dharma. Kudos to Narayanan and Padma for this pious undertaking.

7. I had the wonderful experience of reading "Sanatana Dharma -An introduction to Hinduism" ... ByVijayalakshmi Menonon June 10, 2015 Format: Kindle Edition I had the wonderful experience of reading "Sanatana Dharma -An introduction to Hinduism" authored by Narayanan and Padma Komerath. I am indeed amazed at the years of reading, discerning, introspecting, rationalising and analysing that must have gone into creating such a work. The bibliography bears evidence to the monumental research done, and the deep commitment that must have sprred the effort in bringing out such a book. The book makes enjoyable reading, written as it is in lucid, reader-friendly language---not something usual in books on religion and philosophy, which are usually heavy reading. It will surely be loved by young adolescents and their parents alike. It has a judicious mix of mythological tales, and prayers for young kids, along with the serious subject of religion and philosophy. There is enough to whet the appetite to know more in each of these areas. The authors' scientific background comes out in the extensive research done into facts and data. In the present times when both parents are working, and hard pressed for time, and children in nuclear families are deprived of the learning that used to be derived from stories told by grandparents, such a book is a boon to the young parents, who are desperately looking for aids in imparting to their offspring knowledge of their own heritage, culture, religion and traditions. Yes, the book addresses a felt need, and is sure to fit into its own vey special niche. Comment| 2 people found this helpful. Was this review helpful to you?

8. An Essential Primer on Hinduism ByRamesh N. Raoon June 8, 2015 Format: Kindle Edition Recently, I read that Hinduism is an “inegalitarian” religion. One could let that assertion be for such a reductionist approach to and the understanding of Hinduism is not new. It is the one taken by outsiders with little knowledge and less grounding and sometimes by insiders who have certain political axes to grind. However, if one were to read such a crude depiction of the vast reach and depth of Hinduism in a single, short paragraph included in a textbook on intercultural communication, by a professor teaching at a Catholic University in Wisconsin, one should realize that there is a vast army of detractors from the monopolistic traditions of Abrahamic religions – Christianity and Islam, especially – and academics using Freudian, Marxist, Feminist and other Western approaches, who have carried out and are carrying on an assault on Hindu traditions, beliefs, and knowledge for nearly a millennium. Given the fact that now anyone can have at their fingertips, at the click of a Google search button, access to vast amounts of information, misinformation, and disinformation on almost any subject on earth, it is important that those who “live” Hinduism should begin to tell the world what their lives are all about and the tools available to understand their lives and their belief systems, their knowledge base, and the methods and modes of their practices to understand this cosmos. Prof. Narayanan Komerath and his wife, Padma Komerath, have combined their commendable efforts to doing so. This is not an undertaking of the ordinary kind, for it is difficult to keep a sage distance from one’s world while writing about it. And if that world happens to be as deep as the oceans and as vast as the skies, then the effort needed to both compact that knowledge into an accessible treatise and to choose wisely what knowledge to share becomes as complicated as the questions that the eldest of the Pandava brothers, Yudhisthira, had to ponder and respond to. To begin, therefore, the authors have to encapsulate for the readers what Hinduism is all about. Is it a prophetic religion? Is there one God, or many Gods, and do Hindus worship “idols”? What is the nature of the Hindu understanding of the cosmos, etc? This is what they say: “As best we can define it in an introductory sentence, Hinduism is the essence of human efforts to answer questions. The questions are about why and how we came to exist, our role in the Universe, our relationships to other living beings and to Nature, and the resulting knowledge on how best to conduct ourselves during life. Hinduism is not limited to followers of any single leader or tribe. It has been described as a religion, a philosophy of life, a way of life, a set of rituals, and a highly diverse set of beliefs, of a highly diverse people. It is all of those, and more”. Indeed, and so well-said! In the US, where others have fought recent battles to ensure the balanced and careful narration of Hindu beliefs and practices in school textbooks, in legislative and policy making bodies, and in higher education, one confronts a vast and well-equipped army of Hindu-baiters or reductionists whose goal seems to be either to caricature “Sanatana Dharma – the eternal philosophy” -- or to dismiss it as a complicated mish-mash of unorganized information about beliefs and lifestyles of a heterogeneous group of people who have inhabited the land that is India, and who might have come to that land with information and knowledge from elsewhere. To right these false narratives takes courage, conviction, and commitment. In this book, Narayanan and Padma Komerath exhibit those qualities in commendable form while hewing carefully to culling information from verifiable sources, and organizing, and commenting carefully on the vast reach of Hinduism. This book is not for the academic looking for new knowledge about Hinduism nor is it meant to replace other compendiums, commentaries, analyses, and exegeses on Hindu thought and belief. Instead, it is a well-organized primer for the intelligent but lay reader, old or young, Indian or outsider, Hindu or of other faiths, and is meant to distill the essence of the glorious efforts of those who call themselves Hindu and their wish to understand the world and to transcend the mundane. Written with verve and wit and including relevant and appropriate examples from the tomes of Hindu essentials, “Sanatana Dharma: Introduction to Hinduism”, should adorn bookshelves in every school library and every Hindu parent/adult should invest the time and effort to teach their children and others equipped with this primer in hand.

9. Hinduism (Sanatan Dharma) from Insiders' Prespective ByHanumanon June 7, 2015 Format: Kindle Edition Unlike the Abrahmic religions, Hinduism (Sanatan Dharma) is not based on any one founder, single book, or single point of time. It has evolved over thousands of years through the accumulated spiritual and scientific experiences of many sages and saints. As a result, its scriptures are voluminous. They cover all facets of life, spirituality as well as secular pursuits like science, medicine, astronomy, mathematics, engineering etc. It is, therefore, difficult and often confusing for an average follower of Hinduism to read such vast scriptural books, mainly written in Sanskrit, and try to understand its philosophy, rituals, beliefs and traditions. During the last two centuries several books on Hinduism have been written mainly by the Europeans, outsiders belonging to the Abrahmic faith, which have distorted, denigrated and demeaned it primarily with the ulterior motive to de-franchise Hindus from their faith. This has definitely created a class of misinformed Hindus alienated from the basic tenants of Hinduism. Fortunately, some Hindu intellectuals, scholars and academics realizing the danger to the survival of Hinduism have started writing books on the subject in a simplified and meaningful manner which could be understood and followed by an average Hindu. The authors of the book, ‘Sanatana Dharma- Introduction to Hinduism’, have tried to interpret Hinduism as insiders, practicing Hindus, in a very clear and unambiguous manner. The Komeraths have covered all major aspects of Hinduism in the book including its history, concept of Dharma, main scriptures, divinity, beliefs, traditions, social order, rituals, mode of worship and philosophy without dragging the reader into too many details thereof. As intelligent and discerning Hindus, the authors have frankly and without mincing words criticized some of the social evils which have sprung up in the Hindu society during the last one thousand years. At the same time, they have also analyzed the reasons for these evils, which have nothing to do with the basic tenets of Hindu Dharma but have resulted from the foreign invasions, brutal, barbaric and oppressive foreign rule from 800 CE, which in turn demoralized the majority of Hindus and the consequent degeneration of the society. The book has been written in a very lucid and simple language which makes it easy to read and understand what Hinduism means for an average educated Hindu. I strongly recommend this book to all practicing Hindus as well as non-Hindus who are interested in learning about the most ancient religious faith in the world. The authors have done a great service to the cause of Hinduism- Sanatana Dharma. Comment| 4 people found this helpful. Was this review helpful to you?

10. Strongly recommended. ByArun Guptaon June 7, 2015 Format: Kindle Edition|Verified Purchase In an age when Hindus can no longer count on absorbing their culture from the environment, and when they are interrogated by their non-Hindu neighbors about their religion, beliefs, practices, etc., an Introduction to Hinduism is a must-have even for Hindus. It is a magnificent effort, clear and simple enough for the young reader, but rich enough to hold adults' attention. Comment| 5 people found this helpful.

11. This book is a great for knowing basics of Hinduism and it seems that ... ByDhavanon June 6, 2015 Format: Kindle Edition This book is a great for knowing basics of Hinduism and it seems that author has done a good research while writing this. The book is very easy to read and author makes it an interesting read by delivering the content in form of discussions. It accounts for almost all the major beliefs and practices by different sects and school of thoughts in Hinduism and smartly avoids all controversies. The author does not take side of any particular set of beliefs while giving holistic description. The book presents logic behind beliefs and luckily it is not a preaching type. Almost everything is properly referenced though there is no explicit list of references. This book not only helps Hindus to refine their own understanding and knowledge but also helps non - hindus to get an unbiased view of the religion which is otherwise difficult to get from a preacher. A reader not knowing anything about Hinduism can also easily understand the content as all the Sanskrit words, and basic terms have been briefly and accurately explained This book gives enough starting points to people who wish to research more on a particular aspect of the religion. The author explicitly mentions at various occasions where an interested reader would like to venture out for more information. Clearly, this book is just a base and one should not expect a lot of details. I can confidently say that I got to know significantly more about my religion from this book compared to what I had learn from my parents and other religious texts. Again, this book is not great for preaching (which is nice in a way!) but serves as a good reference for a knowledgeable discussions and debate on the religion. Enjoy...

12. A good book for reference ByH Nairon May 18, 2015 Format: Kindle Edition|Verified Purchase Having two young kids born and raised in the US and now in India, there is a lot of difficulty in explaining "Why?" kind of questions from them, that are sometimes not easy to answer in English. Unfortunately, english is the only language through which they understand the nuances. This book addresses a lack of books in that space. It is something you can gift to a high-school kid, a non-Indian friend interested in Indian dharmic traditions or simply to self! Covers a lot of Sanatana Dharma, in a very no nonsensical fashion. Great buy. Comment| 4 people found this helpful. Was this review helpful to you?

Unique book for all ages written by a research scientist and a teacher ByRam Sidhayeon May 13, 2015 Format: Kindle Edition I would highly recommend this book to any one who is interested in knowing about Hindu Dharma or Sanatan Dharma or Hinduism. It is written for all ages. Parents and grand-parents can read it and explain to children in simple terms (as age appropriate). High school and college students can read it and comprehend concepts even if they have no prior exposure. Furthermore, uniqueness of this book is that there are several verifiable references that can be helpful for further reading and exploring the subject matter. Teachers of Sunday school can also benefit from this book. Authors have taken the approach based on experience as a research scientist and a teacher in explaining a concept to students who may be at different levels. By reading this book one can appreciate the hard work authors have put in to explain complex concepts in a simple language. So, what are you waiting for? Please read the book and encourage your family members and friends to do the same. Thanks. Ram Sidhaye ====================================================== Comment| 3 people found this helpful.
