All that is valuable is esoteric. Ecstasy cannot be pragmatic. Love cannot be pragmatic. Trust cannot be pragmatic. The word esoteric simply means it is not objective, not scientific. It is something inner, something subjective, something so mysterious, so miraculous that you can experience it but you cannot explain it. You can have it, but still you cannot explain it. It remains beyond explanation. It is good that there is something in life which we cannot bring down to language, which we cannot bring down to the objective world, something which remains always beyond. We can become one with it – and that Osho describes as the work of his school.This early work by Osho is a University course in psychology and esoteric - two words which seem not to fit together at all, but Osho integrates everything in a way the human mind cannot. The subjects and areas addressed by Osho in this book cannot be described on the back cover of a book, it is only possible to indicate, to give a glimpse. This book is about becoming and being, an introduction to an understanding which allows a new view of ourselves and the existence around us. Why do we suffers from anxiety? We seem to be anxious to our very roots. What torments us, to begin with, is: To be or not to be? To do or not to do? To do this or to do that? “No choice” is not possible. If we do not choose, then we are choosing not to choose; it is a choice. So we are forced to choose; we are not free not to choose. The dignity, the beauty and the glory of humans is this consciousness. But it is a burden also. The glory and the burdencome simultaneously the minute you become conscious.Osho speaks in this elaborate work about human revolution and as he uses the word here, it means a conscious, an effort toward an individual evolution. It is bringing individual responsibility to a peak. Only we are responsible for our own evolution. Ordinarily, humans try to escape from responsibility for their own evolution, from the responsibility of freedom of choice. While we long for freedom, there is a great fear of freedom. When we are slaves the responsibility for our life is never ours; someone else is responsible. So in a way, slavery is a very comfortable thing, there is no burden. In this respect, slavery is a freedom: freedom from conscious choice.

In this book about the Sarvasar Upanishads Osho describes the search within, the search for the essence, for what is divine within man. "I warn you in advance that to involve oneslf in the teachings of an upanishad is like playing with fire. An Upanishad cannot be understood without you also becoming transformed."
