[Ten principal seats of the life forces] There are surely ten principal seats in which the life forces are established. The two temples, the three vital organs, the throat, rakta dhatu (blood), shukra dhatu (reproductive fluid), oja (the vital fluid) and the anus.
The learned person who knows these as well as the sensory and motor organs, intelligence, the cause of consciousness as well as diseases is known as the companion of the life forces.
[Two types of doctors] Surely, there are two types of physicians, Agnivesha! One who is a companion of the life forces and destroyer of diseases, and the other who is the companion of diseases and destroyer of the life process.
