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.
Intestinal villi (singular: villus) are small, finger-like projections that protrude from the epithelial lining of the intestinal wall. Each villus is approximately 0.5-1.6 mm in length, and has many microvilli projecting from the enterocytes of its epithelium which collectively form the striated or brush border.Each of these microvilli are much smaller than a single villus.illi are specialised for absorption in the small intestine as they have a thin wall, about one cell thick, which enables a shorter diffusion path. They have a large surface area so there will be more efficient absorption of fatty acids and glycerol into the blood stream.
