Breath is likened to water. The flowing of the breath is like the flowing of a stream. Inhalation and exhalation show ebb and flow. Parts of the earth which water does not touch remain barren; so the centers in the body, with all their intuitive, innate capacities, remain unproductive if the breath does not reach them. Besides various diseases, in spite of all their apparent causes, often have one principal cause, and that is the lack of free flow of the breath. Many operations could be avoided and several diseases could be cured by the knowledge of the phenomena of breath.

The Hindu sacred rivers, Ganga and Jumna, are outward symbols of Jelal and Jemal, the two directions of the flow of the breath. And the place where they meet is called Sangam, the meeting or unity, which is considered most sacred by the Hindus. That Sangam is the meeting of these two opposite flows. It is like the meeting of the two directions in the center, which is called Kemal by the Sufis.

The water rises, passes, falls, and runs zigzag, and stands if held. So is breath. Every above-said action of breath has a meaning and has a peculiar effect, as even water varies in its power and magnetism while going through the above-said directions.

Water is a tonic, and breath is life itself. No tonic can be greater and better than breath. A spiritually evolved person's presence, therefore, brings about a cure in cases where all remedies fail.
Water is the necessity of life, and breath the only condition for living. Without it life is impossible.
Water falls as a rain from above; so breath is from above also, though from another dimension.
Water rises as vapors; so breath rises with gases, also with joys or depressions.
Pure water is health-giving, pure breath gives life.
Water partakes of all things mixing with it; so does breath.
