May I ask why my comment was deleted? I was merely pointing out that taichi being descibed as "a moving form of yoga and meditation combined" would, by all accepted understandings of what is, and is not, taichi, would be incorrect.
Taichi is a martial art, and while combat application training is not necessary, an understanding of the martial intent of the art is necessary for it to be considered taichi. Otherwise, it is yoga, or meditation, or dancing with fans, and should be called such so as to not mislead peple, IMHO.
