Ba Gua: Hidden Knowledge in the Taoist Internal Martial Art
by Sing-Han Liu, John Bracy
1998
The Taoist yogic discipline of Ba Gua is an internal form of the ancient art of kung fu--as are the much older t'ai chi and Xing I. Ba Gua is the most arcane and yogic of three sister arts--t'ai chi and Xing I are the others--and is distinguished by serpentine turning and circling momvements and its own internal energy exercises, Ba Gua Qi Gong.
