This book traces the broad outlines of the Wisdom Religion and explains its fundamental principles, meeting, at the same time, the various objections raised by the average Western Enquirer, and endeavouring to present unfamiliar concepts in a form as simple and in language as clear as possible.
Nonviolent activist Mohandas Gandhi spoke of it in his autobiography:
"This book stimulated in me the desire to read books on Hinduism, and disabused me of the notion fostered by the missionaries that Hinduism was rife with superstition."
