Noun

1. a form of meditation as practiced in Zen Buddhism.

   • 1992: In the practice of Zen there is an exercise called zazen – similar, I think, to the Theravedic practice of vipassana. One sits facing a blank wall. No matter the emotion one feels, no matter how strong or violent, one remains motionless. Facing the wall. The discipline, of course, is in continuing to sit. — Donna Tartt, The Secret History
