20.1

Now we shall explain the chapter named 'The Classification of the Doṣas'.
Thus said Ātreya and the other great seers:
Vāyu is from the wind and space elements;
pitta is fiery;
śleṣman is from water and earth.
There, the colon, pelvis, thighs, feet, bones, ears, and the organ of touch are the seats of vāta;
and among these, especially the colon.
The navel, stomach, sweat, lymph, blood, eyes, and the organ of touch are the seats of pitta;
among these, especially the navel.
The chest, throat, head, trachea, joints, stomach, fluid tissue, fat, nose, and tongue are the seats of śleṣman;
here too, especially the chest.
In this manner, by the triad of doṣas residing in the lower, middle, and upper [regions], the body is made stable like a house by three pillars.
And for this reason, because of making the body stable, the doṣas are called pillars;
because of sustaining [the body], they are [called] bodily tissues;
because of causing pollution and being the waste product of food, they are waste products;
and because of their nature to vitiate, they are doṣas.
Thus said Ātreya and the other great seers.
