Hatha Yoga is a specific system of exercises, the main components of which are body positions, pranayama (breath control) and meditation (calming the mind). It can be said that Hatha Yoga leads us home if we allow ourselves.
Qigong, chi kung, or chi gung is a practice of aligning breath, movement, and awareness for exercise, healing, and meditation. With roots in Chinese medicine, martial arts, and philosophy, qigong is traditionally viewed as a practice to cultivate and balance qi or what has been translated as "intrinsic life energy".
I practice a 10-minute morning routine "Eight Pieces of Brocade" with the addition of several other exercises according to the moment's feeling.
