I recall reading in one of Kam Yuen’s books that the ideal state of the healer is to be neutral to the one he would help. It is like unconditional love or peaceful revolution.
The focus is on transformation rather than judgement. If you are negatively judging another person it becomes difficult to affect positive transformation.
Focus on the midline and place the energy of thought there for deleting or strengthening as the needs of the individual demand. Transformation is instantaneous.
the following is another youtube video where Kam Yuen is demonstrating his transformational or healing techniques. http://www.youtube.com/watch?v=HR9RNcrbRPA&feature=related
