The Tai Chi and Yin and Yang
Eastern philosophies focus many of their assumptions about the concept of complementarity, balance between opposing joint force or, in the language of the same, Yin and Yang. These opposing forces are present in all that exists, and complement giving the whole a sense of unity.
Because tai chi is one of the expressions of Eastern wisdom, obviously not free from this logic of opposites. In fact, the Yin and Yang are the alma mater of tai chi, and all the exercises in this discipline have a quota of opposites interact.
So when did a tai chi exercise unconsciously combine parts of yin and yang own martial art, and this balance and balance brings us into extreme concentration and introspection. Each move has value in terms of yin and yang, and also the center of gravity, which unites the two opposites.
In fact, in all forms and exercises that takes the tai chi, yin and yang is inherent in it that sets the sensitivity required for each of the movements.
Of course, the tai chi is not the only Eastern practice that contains this principle of opposites. Yoga and other martial arts also play with him, in fact, is one of the founding forces.
