Zen is not a particular state but the normal state: silent, peaceful, unagitated. In Zazen neither intention, analysis, specific effort nor imagination take place. It's enough just to be without hypocrisy, dogmatism, arrogance - embracing all opposites.
Taisen DeshimaruWhat is called zazen is sitting on a zafu [pillow] in a quiet room, absolutely still, in the exact and proper position and without uttering a word, the mind empty of any thought, good or wicked. It is continuing to sit peacefully, facing a wall, and nothing more. Every day.
