Letting Intent Surface

"Chen Style Taijiquan: The Source of Taiji Boxing" has the following description of how Xin (mind) and Yi (intent) are harmonized:
"One must quiet and relax the mind. When the mind is calm Yi (intent) surfaces. One can then concentrate and focus the Yi" (D. Sim & D. Gaffney, pg 69)
It is a good reminder that what you don't do is very important in the internal arts. Overthink and you will not get anywhere. Still the mind and opportunities will follow.
The book the above quote comes from provides an excellent overview of central Taiji training concepts. It smartly avoids trying to teach the forms and focusses on being a resource for students. Certainly one of the better books on Taijiquan in English.
