According to Tibetan medicine, mind and body are often disturbed by the improper functioning of the three bio-energies — Loong, Tripa and Baekan.
These "bio-energies" are known as humours. In ayurveda, they are called "vatta", "pitta", and "kapha". These terms are translated into English as "wind", "bile" and "phlegm". Each humour is further classified into five categories which enable the physician to assess in a more accurate manner, the patient's condition.
How the humours are combined in an individual will determine his or her disposition, physiological type and so on. When the humours are working as they should, they are said to be in balance. When they are not, a doctor or a lama may need to intervene.
Tibetan doctors explain the connection between the humours and the three poisons in the following manner: the three mind poisons actually create the humours: ignorance (or close-mindedness) is the source of phlegm; desire, of wind; and aversion (or hatred), of bile. Since the three poisons work at this root level, they are classified as the distant causes of disease.
Even after death, we are not free of ourselves. Our basic predispositions linger on in the bardo and propel us to our next rebirth.
