Yoga is divided into several branches, ranging from that which teaches the control of the body, to that which teaches the attainment of the highest spiritual development. In the work we will not go into the higher phases of the subject, except when the "science of breath" touches upon the same. The Science of Breath touches yoga at many points, and although chiefly concerned with the development and control of the physical, has also its psychic side, and even enters the field of spiritual development. The first part of the book is devoted to the physical phase of the science of breath; then the psychic and mental sides are considered, and finally the spiritual side is touched upon. We may be pardoned if we express ourselves as pleased with our success in condensing so much yogi lore into so few minutes, and by the use of words and terms which may be understood by anyone. Our only fear is that its very simplicity may cause some to pass it by as unworthy of attention, while they pass on their way searching for something "deep", mysterious and non-understandable. However, the Western mind is eminently practical, and we know that it is only a question of a short time before it will recognize the practicability of this work. We greet our students, with our most profound saalam, and bid them be seated for their first lesson in the yogi science of breath.
