The dan tien is the basis of the Horse Stance. The Horse Stance is the basic stance for all martial arts, including Tai Chi. It aligns the three dan tien points, upper, middle, and lower (see video in column to right), to give you the best posture and most effortless, yet powerful, movement.

Note that the head is drawn upward toward the sky, as if a string were pulling from the center of the head. The chin is slightly pulled in, and the tailbone or sacrum is dropped down. This has the effect of lengthening the spine.
