Because so many in the world believe their diseases are occasioned by imbalance, it is necessary to understand the process of restoring harmony. The body is symmetrical and asymmetry may need to be repaired to restore self esteem. Whether it is Starling’s Law, the concept of homeostasis by Claude Bernard or the Greek concept of symmetry, the desirability of balance pervades many systems of medicine. These ancient systems seek harmony of man, earth and cosmos.
In Ayurveda the three constitutional types (Doshas, Vata, Pitta, Kapha) should be in equilibrium and may be aggravated or diminished. There are channels along which energy should flow and there are wastes that must be eliminated.
It is surprising how many similarities there are in for example the Chinese system and Indian systems of Medicine or the beliefs of primitive people about inter-relationships and the environment.
Warning Failure to understand the importance of balance in the delivery of Public health will result in mistakes in the management of culture, customs, religions, beliefs and ideals. When examining other systems of medicine it is also looking at other ways of life with attention to physical, mental, social and spiritual well being.
Action When applied to medicine good health is perfect harmony with a rejection of excesses inclusive of diet and sexual activities. It perceives an ebbing and flowing between Yin and Yang. In the form of energy it must flow freely along invisible channels. Yanchi (1988) writes ‘disease occurs when the dynamic equilibrium within the body and environment fails, damaging the normal physiological functions to the point that there is an imbalance between Yin and Yang’.
