Among the Yogis of India, the system of Physical Well-Being known as "Hatha Yoga," in its many phases and forms, is followed, practiced and taught. Thousands of natives of India know no other form of physical culture, or methods of hygiene, and maintain health and physical vigor by an adherence to its precepts. In connection with Mental Healing, this system forms the great Natural Healing school of the Hindus. In our work on "Hatha Yoga," we have explained that system in general, and in many of its details.

There is one form or phase of "Hatha Yoga," however, which constitutes an important part of this great system of Natural Healing, which should be understood and practiced by those who would maintain a healthy condition of physical being, and which is worthy of being explained in detail in a supplementary volume-the Hindu-Yogi system of Practical Water-Cure. In response to many demands from those who were interested in our presentation of the general subject of "Hatha Yoga," we have incorporated in this supplementary book the details of the said system. We trust that we will bring to the attention of many persons of the Western world the benefits to be derived from this most meritorious system.
