Hi Aliza, The subject is the name of a well written booklet regarding the basic aspects of Tai Chi. It is published by: Henry Holt & Company, Inc. 115 West 18th Street New York, NY 10011 Written by David Carradine and David Nakahara I'm sorry, but I do not know of where to purchase the Tai Chi Tape. Bear in mind that nothing can replace that of a qualified instructor. As to the question about names of Tai Chi organizations, I am presently in the process of trying to achieve that goal. I'll forward that information to you when I get it. Meanwhile, good luck to you. Jerry Di Lauro ([log in to unmask])
