1 becomes 3; 3 becomes 1
This is the activity of Zen. The nondifferentiated awareness alternates with self, subject and object.
This is commonly expressed through breathing. The ultimate small of emptiness breaks apart into inhalation, object which becomes the exhalation, subject that the self experiences. Then the ultimate large of the universe’s emptiness manifests. The ultimate small and ultimate large happen where the breath pauses, at its end point.
Rinzai’s Four Conditions
“Sometimes I snatch away the person but not the environment.” (Pure sight, sound, etc.)
“Sometimes I snatch away the environment but not the person.” (Pure activity like shouting)
“Sometimes I snatch away both person and environment.” (Emptiness, ultimate small)
“Sometimes I snatch away neither person nor environment.” (Emptiness, ultimate large)
