Yin and Yang, with Yang in the ascendant phase.
The first principle of Tai Chi Chuan is Tai Chi, which is the interaction of Yin and Yang in the constantly varying process of natural equilibrium.
An attack is by its very nature is definitively Yang. By accommodating, redirecting, or avoiding the attack (becoming Yin) we encourage the attacker to enter the Yin phase, by over extending, becoming unbalanced, or simply needing to recover before his next assault. During his Yin phase we may become Yang and counterattack.
