The second guna is rajas, that is the stage when man starts the active process of self-development, transcends dumb primitiveness, grows as a warrior, and then as a leader, organizer of other people. The third guna is sattva, that is purity, harmony, bliss, happiness.
Villi also help the food to move along the digestive tract. Food takes three to six hours to move through the small intestine. The small intestine has three parts, the duodenum, jejunum and ileum.
Villi, the singular of which is villus, are finger-like projections in the small intestine that help absorb food more efficiently in the body. The small intestine is an organ in the body in which most digestion occurs. Food entering into the body is liquefied and partially digested in the stomach. It then passes into the small intestine. The villi are the parts that absorb nutrients from food and pass them into the bloodstream.
