Description
The yin and yang concept advocates the necessity of having both elements present to encompass an ideal balance. Relating it to a simpler understanding of hot and cold, where neither extremes are desirable but a combination of both, produces the warmth desired. Other basic ways of explaining yin and yang are, yin being soft and yang being hard, yin being stillness and yang being movement, yin being the sun and yang being the moon, yin being day and yang being night and so on.
