Chinese sciences and traditions are based on a dualist concept of the world where two opposing principles balance in a dynamic way. Yin and the Yang principles are present in everything, in varying proportions. Harmony between these two principles arises from the constant search for equilibrium between them.
Feng Shui attempts to achieve this equilibrium where we live and work. It is related to space, and to our internal and external environments.
But Feng Shui also belongs to the dimension of time, anticipating an unbalance stemming from the dynamic Yin and Yang principles.
Yang is the bright, hot, dry side of life. Its principle is that of birth and renewal, it is more active in summer and tradition associates it with the Dragon.
Yin is the shady, wet, cold side of life. Its principle is that of disintegration, it is more active in winter and tradition associates it with the Tiger.
The Feng Shui practitioner will look for the external and internal placement of living and working environments.
The continuous flow of Yin and Yang transformations creates all the changes which affect the whole world.
Feng Shui is much more than just an art of placement. It is a study of the environment and how the energies of the environment interact with the individual dwellings. Feng Shui is indeed a highly complex art, which requires a sound understanding of the fundamental principles before one can ever attain mastery over the field.
