Should I concentrate on the “Third Eye” between the Eyebrows?

One must be careful when concentrating on this point. The power

tends to flow upward and if it is obstructed, possibly because the

palate is too thick, and it is harder for the Chi to penetrate it then to

rise up and push open the Pai-hui in the crown of the head. This

forces it to flow out of the body for some time, and may cause

pressure to build in the head. Therefore, young people, strong virile

types, those with high blood pressure and those with mental problems

should not concentrate on this point.
