In Zen <http://en.wikipedia.org/wiki/Zen> Buddhism
<http://en.wikipedia.org/wiki/Buddhism> , the keisaku (Japanese
<http://en.wikipedia.org/wiki/Japanese_(language)> : è¦ç, Chinese
<http://en.wikipedia.org/wiki/Chinese_language> : 馿¿,
xiÄng bÇn; kyÅsaku in the Soto school
<http://en.wikipedia.org/wiki/Soto_school> ) is a flat wooden stick or
slat used during periods of meditation to remedy sleepiness or lapses of
concentration. This is accomplished through a strike or series of
strikes, usually administered on the meditator's back and shoulders in
the muscular area between the shoulder blades and the spine. The keisaku
itself is thin and somewhat flexible; strikes with it, though they may
cause momentary sting if performed vigorously, are not injurious. -
