You have an unusual edition in your hands. You have probably looked at various conferences on the Internet, however, a yoga book created on the basis of such a conference is the first time. We are sure that reading this book will not be boring for you. There is an open controversy, and rather caustic texts, and - what is important! - materials are extremely interesting and informative points of view of a person who is interested in yoga and practices it. As for the controversy, which is enough here, as you know, truth is born in it, especially if the debating parties have devoted many years to the subject under discussion.
