The Yoga Sutras of Patanjali: The Book of the Spiritual Man

Although the English version of this book was published more than a century ago (1912), it is, in fact, one of the oldest books in history, as it presents the truths that have been a part of the seminal oral book of Indian practical philosophy, which was practices about two thousand years ago. Despite its old age, the book expresses universal truth and is still topical today.
