Hsing qi is the very foundation of the internal arts. Motion and presence are often the vehicles which give occult significance to even the most basic techniques, such as breathing. Be it taiji chuan, bagua, nei gung, yoga, or some other style of practice, the principles of hsing qi are the guiding principles of them all.
One of the basic principles of hsing qi is simply this: where the mind goes, energy follows. Extraordinary feats can be accomplished when the practitioner of hsing qi disciplines him/herself through consistent daily nurturing of vital force so that the maximum amount of energetic potential is under the direction of a conscious and focused mind. Life force will cease to be squandered, vitality will continuously build to extraordinary levels, and willful actions will have the momentum of the universe behind them.
