This is a book written by the famous Annie Beasant and Bhagwan Das. "The wisdom of inspired Seers is recorded in various Samhitas, Sutras, Smrtis, and other fragments.  The corpus of all these is Sanatana Dharma, Eternal Order, or Dharma.  Through millennia, Hindu society was moulded by it.  Thought necessarily Indian in garb, its principles have a timeless relevance to any society, anywhere, any time.  It is striking that the first-ever serious attempt at drawing from the vast, nebulous, scattered sources the principles of Sanatana Dharma and codifying them was left to Annie Besant, foreign by birth, but more truly Indian than an Indian could be.  In compiling this brilliant work, she was ably assisted by a team of eminent Sanskrit scholars headed by no less a savant than Bharata Ratna, Dr. Bhagavan Das.  A reading of this book is in itself a liberal education."

This book is edited by Jaganniwas Iyer. "With the changing times, we seem to be too engrossed in our silos of individual growth and achievements and tend to ignore or even ridicule tradition. To be Western is the trend, without realising that the philosophical tradition of the West is trying to discover the beauty of Sanatan Dharma—an all-inclusive way of life. From Adi to Anant, Sanatan Dharm is the constant evolution and revelations of human possibilities. It keeps transforming with time to suit the need for existence. It is not rigid. But the moral order underlying existence never changes. When duty becomes a part of consciousness and gets the backing of impeccable philosophy of existence, life becomes much easier. Sanatan Dharm does just that. As we step into this new world, Sanatan Dharm will find increasing resonance with those who wish to understand religion and its purpose in life. This is because Sanatan Dharm is not prescriptive and gives individuals the liberty to be seekers and find their own enlightenment. It rather guides people to attain higher levels of spiritual discovery."
