Faeces represent the undigested waste or residue of food. In the process of digestion, material from the amashaya (stomach), having reached the pakwasaya (large intestine) is dried up and is converted into lumps.
After digestion, the food is converted into ahara-rasa and
kitta.
Ahara-rasa is the portion, which contains nutrients for dhatus i.e. body tissues.
Kitta is the portion, which contains constituents of and nutrients for doshas, i.e. vata, pitta and kapha and stools, urine, gases, sweat, hair, nails and waste products of nose, eyes, ear, mouth and skin.
Pureeshadhara kala i.e. lining of the colon differentiates faeces from other components of kitta. It extends from lower part of small intestine to pelvic colon.
After absorption of all the essential components with the help of samana vayu, the portion that remains is termed as pureesha or
faecal matter.
