Famous philosophers are students of Bhagavad-Gita:

When I read the Bhagavad-gita I ask myself how God created the universe. Everything else appears to be superfluous. -- Albert Einstein.

It was the first of books, it was as if an empire spoke to us, nothing small or unworthy, but large, serene, consistient, the voice of an old intelligence, which in another age and climate had pondered the same questions which excercise us. -- Ralph Waldo Emerson.

The book which, in a whole lifetime, has given me the greatest enlightenment. -- Johann Wolfgang von Goethe

It is the most informative and sublime book in the world. -- Arthur Schopenhauer

Bhagavad Gita As It Is is used as a text book by colleges and universities.

"No work in all Indian literature is more quoted, because none is better loved, in the West, than theBhagavad Gita. Translation of such a work demands not only knowledge of Sanskrit, but an inward sympathy with the theme and a verbal artistry. For the poem is a symphony in which God is seen in all things....The Swami does a real service for students by investing the beloved Indian epic with fresh meaning. Whatever our outlook may be, we should all be grateful for the labor that has lead to this illuminating work."
Dr. Geddes MacGregor, Professor of Philosophy, University of Southern California

"I am most impressed with A.C. Bhaktivedanta Swami Prabhupada's scholarly and authoritative edition of Bhagavad Gita. It is a most valuable work for the scholar as well as the layman and is of great utility as a reference book as well as a textbook. I promptly recommend this edition to my students. It is a beautifully done book."
Dr. Samuel D. Atkins, Professor of Sanskrit, Princeton University

"I have had the opportunity of examining several volumes published by the Bhaktivedanta Book Trustand have found them to be of excellent quality and of great value for use in college classes on Indian religions. This is particularly true of the BBT edition and translation of the Bhagavad Gita."
Dr. Frederick B. Underwood, Professor of Religion, Columbia University

"...If truth is what works, as Pierce and the pragmatists insist, there must be a kind of truth in theBhagavad Gita As It Is, since those who follow its teachings display a joyous serenity usually missing in the bleak and strident lives of contemporary people."
Dr. Elwin H. Powell, Professor of Sociology, State University of New York
