tiger stare

From my 1961 martial arts notebook:
TORA NIRAMI (Tiger Stare) Take kneeling position facing each other, give KIAI and keep all stomach muscles tensed while staring without blinking at a spot between the eyes; and this is a form of hypnotism, and the stronger will overpower the weaker. Do not use in social gatherings or normal conversation as it will cause people to be afraid of you.

I found that "keep all stomach muscles tensed" is more accurately translated as "keep one-point" -- all action comes from the hara, the tan t'ien.
