v2.c34.236

When the blood has been formed, the essence of chyle in the blood, acted on by Váyu (biomotor force) and Mámságni (the flesh forming metabolic heat), forms the flesh-tissue, the Earth-compound of the food substance especially contributing to this tissue of the flesh tissue thus formed, the grosser part goes to feed or replenish the flesh tissue all over the body. The finer essence of flesh in the blood in the chyle, acted on again by Váyu (biomotor current) and the fat-forming metabolic heat (मेदाग्नि) in the menstruum of lymph (कफ समाश्रय), receives viscosity and whiteness, and produces the fatty tissue, the Earth-compounds and Ap-compounds of the food especially contributing to the product. This fat in the chyle (or blood), or rather the grosser part of it replenishes the fatty tissue of the body, but the finer essence of fat in the flesh in the blood in the chyle, acted on by Váyu (biomotor current) and the marrow-forming metabolic heat, in the menstruum of lymph (श्लेष्माण्वृत), becomes hard (or crystalline), and forms bone, the Earth, Váyu and Tejas compounds contributing principally to the product. The essence of the fat fills the hollow channels of the bones, and acted on again by biomotor Váyu and metabolic heat, becomes transformed into the marrow. The marrow is transformed into the semen, which is conveyed down by means of a pair of Dhamanís (ducts) (द्वे शुक्रवहे), lodged in its receptacles (शुक्रधरा—वृषणौ) and discharged by means of another pair of ducts (द्वे विसर्गाय). The semen, or rather all the elements in their finer essence, give off Ojas, which returns to the heart, the receptacle of chyle and blood, and again floods the body, and sustains the tissues, thus completing the wheel(or self-returning circle ) of metabolism ( परिवृत्तिस्त चक्रवत्. Cf. Charaka and Vāgbhata ).
