“In sharp contrast to conventional biomedicine where the active ingredient (for example, ibuprofen) is believed to do nearly all the work, in Tai Chi, intention and belief are considered highly active and specific ingredients. In fact, Tai Chi classics emphasize that all embodied movement begins with belief, thought, or intention: The mind (yi, intention) leads the Qi, and the Qi moves the body. This central role of belief and expectation precludes the possibility of designing placebo-controlled studies of Tai Chi."

--- Wayne, Peter M. “The Harvard Medical School Guide to Tai Chi".

To me, this is the most amazing part of taichi practice: imagination determines your body's performance.
