According to Ayurveda the body is made up the five elements of Ether, Air, Water, Fire and Earth. The various encounters the body and mind experience and the emotions it puts itself through cause the body and mind to wear and tear and express a dis-ease condition.
If we don't learn from this dis-ease condition, and instead identify with the effect alone, then the dis-ease, with time, manifests itself into an illness.
Eventually, when the learning happens, the illness has no more reason to stay on and so, the body cures itself.
Chikitsa in Ayurveda means therapeutic intervention. Chikitsa is a process that helps at 3 levels; Body, Mind and Spirit.
The most important factor in therapeutic intervention is to derive the knowing of which of the therapeutic elements to use and how. An adept in Ayurveda can seek out these answers from Consciousness (Brahman) which is the source of all knowledge.
