THE YOGI THEORY AND PRACTICE OF PRANA ABSORPTION FROM FOOD
NATURE'S shrewdness in combining several duties into one, and also in rendering necessary duties pleasant (and thereby likely to be performed) is illustrated in numberless ways. One of the most striking examples of this kind will be brought out in this chapter. We will see how she manages to accomplish several things at the same time, and how she also renders pleasant several most necessary offices of the physical system.
Let us start with the statement of the Yogi theory of the absorption of Prana from food. This theory holds that there is contained in the food of man and the lower animals, a certain form of Prana which is absolutely necessary for man's maintenance of strength and energy, and that such form of Prana is absorbed from the food by the nerves of the tongue, mouth and teeth. The act of mastication liberates this Prana, by separating the particles of the food into minute bits, thus exposing as many atoms of Prana to the tongue, mouth and teeth as possible. Each atom of food contains numerous electrons of food-prana, or food energy, which electrons are liberated by the breaking-up process of mastication, and the chemical action of certain subtle chemical constituents of the saliva, the presence of which have
