Many people, including some Zen students, may be unaware of the following two historical facts. One, all schools of Zen today issued from the Shaolin Monastery. Two, Shaolin Kungfu started as a result of Zen. Shaolin Kungfu and Zen, as well as Chi Kung, are intimately connected, although some kungfu instructors today may not know this connection, and therefore teach Shaolin Kungfu as a purely external art, deprived of its internal and spiritual aspects. At its elementary level, every kungfu movement involves energy control and mental awareness.
