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 are located in different areas of the body. Most commonly, the term is used to describe the many tiny, fingerlike structures that stick out and are located in groups over the entire mucous surface (a type of thin sheet of tissue) of the small intestine.
