F.  Crest (Fig. 4.4)

Using your thumbs, massage the crest (the edge) at the base of the skull until you feel no pain there. (Fig. 4.5) This will help you reduce headaches and eye aches and will increase vision. This place in Tao tradition is called the Pool of Wind which tends to collect the “evil wind”, the major cause of all the pain in the senses.
