Every Dosha is divided into five sub-Doshas. Kapha = Water+Earth
1. Bodhaka Kapha The form of water that gives perception. It is located in the mouth and tongue as the saliva that allows us to taste our food. Like Kledaka, it is also a part of the first stage of digestion. It also helps to lubricate the other sensory openings in the head.
2. Kledaka Kapha The form of water that moistens. It is located in the stomach and, as the secretions of mucous lining, in the gastrointestinal tract as well as Rasa Dhatu. It is responsible for the liquefaction of food and for the first stage of digestion, absorption and assimilation of foodstuff. Taste is related to Rasa Dhatu and Bhodaka Kapha is directly connected to Rasa.
3. Avalambaka Kapha The form of water that gives support. It is located in the heart and lungs. It is the storehouse of Kapha (phlegm) and upon it depend the actions of the other Kaphas in the body. It is not simply the phlegm produced by the lungs, as that is an excess of Kapha generally. It corresponds to the basic plasma of the body, its primary watery constituent, which is distributed by lung and heart action. Another location of Avalambaka Kapha is the lower back.
4. Tarpaka Kapha The form of water that gives contentment. It is located in the brain, as cerebro-spinal fluid, the white matter, and in the heart. It governs emotional calm, stability and happiness, as well as memory. Tarpanam means nourishing, including the senses. All sensory perception – auditory, tactile, optical, gustatory, and olfactory – are carried to Tarpaka Kapha by Prana Vayu. Functionally, Tarpaka is connected to the astral body, all past life memories, experiences and knowledge are stored within the matrix of Tarpaka Kapha. The practice of Yoga also increases the mental form of Kapha as contentment and bliss (Ananda).
5. Shleshaka Kapha The form of water that gives lubrication. It is located in the joints as synovial fluid and is responsible for holding them together.
