In coaching, the energy is not physical but the coachee's words can be as sharp as any t'ai chi sword. The coachee can throw the coach 'off balance' by 'hooking' the coach's own thoughts and by distracting or offending. For example, Ian tells of a coaching session when he was thrown off balance when the coachee talked about the suicide of a close relative. For a moment a coach may be only aware of his or her own thoughts rather than being outwardly aware.
A coach needs to be aware of when he or she is knocked off balance and quickly regain a good posture. Like the martial artist, the coach is looking to stay detached and balanced so as to maintain their coaching presence throughout the session. And then there comes the moment when the martial artist, grounded in the soft 'yin' energy of relaxation, awareness and balance, chooses to tense the muscle and consciously direct hard 'yang' energy to impact the opponent through a measured 'strike'.
