This book serves as the logical conclusion of the trilogy “The Practice of Hatha Yoga”, in which the books “Student Among Teachers” and “Student in Front of the Wall” were previously published. If the first was devoted to practical orientation among the variety of modern styles of hatha yoga, and the second provided an option for building an independent practice, then the third will talk about sustainability when interacting with Indian spiritual traditions, which have border areas with hatha yoga. The concept of understanding is also developed here hatha yoga as a “practical philosophy” or “philosophy of the body,” introduced in the author’s scientific work “The Basic Schools of Hatha Yoga.” The book is written on personal experience of contacts with representatives of all traditions during the author’s residence in India and is equipped with many photographs depicting unique teachers and temples.
