Infinite are the points of a circumference and infinite are the ways that from them lead to the center. Taiji, martial art and practice of inner transformation is, among the genuine paths, a Supreme Way, as smooth and in balance, Yin and Yang. A path that advances when the opponent retreats and withdraws when the opponent pursues, to become one with it: the dissolution of duality created by the ego, the end of illusions, and the natural appearing of the Deep Mind, of the Spirit, of God.

Defeat 1000 pounds using 4 ounces, this is the Way of Taijiquan, Yin and Yang. Where the opponent is strong (yang), the practitioner of Taiji is not there, like a ghost, where the enemy is weak (yin) the practitioner of Taiji drives his strength, like a river in flood. The adversary can not find any resistance to apply its apparent strength, falling out from its center and discovering its real weakness. Free from superficial mind that imprisons him and makes him clumsy the practitioner of Taiji becomes formless water, he flows away without resistance and penetrates deeply, creating a strong vortex as a center: unstoppable but constantly adapting he thus manifests his True Strength.

The kindness overcomes the brute strength, what is formless cannot be stopped
