Cut up on the old stone drums of Republic of China, inscribed in books handed down through thousands of years, traced on ancient saucers and on saucers made today, is a sign and a symbol. It is woven into textiles, stitched into embroideries, emblazoned over house gates, wrought into shop emblems, a circle, locked together inside it yang and yin yang, light, yin, dark, each carrying inside itself the essence of the other, each shaped to the other.
Yin and Yang is a popular ancient Chinese construct of two complementary forces in the universe, which work hand in hand, to produce favorable energy.
Simply put, one force is favorable or differently referred to as masculine while the other is negative or differently referred to as feminine. Neither is preferred or is better than the other, and both are highly desirable factors when it exists in perfect harmony and balance.
This construct of equal balance between negative and positive factors is of course contradictory to most existing fundamentals where good is forever sought in its complete form. The yin and yang concept however advocates the necessity of having both factors present to embrace an ideal balance.
Relating it to a simpler comprehending of hot and cold, where neither extremes are desirable but a combination of both, produces the warmth desired.
Additional basic ways of explaining yin and yang are, yin being soft and yang being hard, yin being stillness and yang being motion, yin being the sun and yang being the moon, yin being day and yang being night and so on.
The Start Point
The cycle duplicates itself. Where one leaves off the other begins and vice versa. This opposite attracts and binds well concept is reflected in many ancient Chinese sciences and philosophies. Traditional Chinese medicine, Chinese martial arts, exercises are just a few that follow this concept.
A more romanticized description of yin and yang use the sunlight over a mountain scene. It's explained as when the dark side of the mountain changes into a brightly lit up side, this simultaneous movement that seems to “melt” into each other is depictured as yin and yang infused and moving comfortably to accommodate each alteration harmoniously.
The most popular pictorial display of yin and yang is the two tadpole like drawings that imply the uninterrupted cycle of each flowing into the other in harmony. The colors used are also significant in its choice, which are black and white. Two really distinct and contrastive shades.
