"Tea practice still has value as a meditation
exercise. Nonthinking repetition of mechanical
forms allows one to concentrate simply being
without the distraction of having to make
decisions, artistic or otherwise.
This aspect of the practice is based on the
belief from Zen that the body, not language,
is repository of knowledge and technique.
Hence tea focuses on the rote learning of forms."
- Leonard Koren

I love this understanding of the value of
"nonthinking repetition" it confirms my belief
in and love of practicing Tai Chi forms so well
known that the body does them by itself.
