The true purpose of Zen is to see things as they are, to observe things as they are, and to let everything go as it goes. Zen practice is to open up our small mind.
Shunryu SuzukiTo stop your mind does not mean to stop the activities of mind. It means your mind pervades your whole body.
Shunryu SuzukiThe mind we have when we practice zazen is the great mind: we don't try to see anything; we stop conceptual thinking; we stop emotional activity; we just sit. Whatever happens to us, we are not bothered. We just sit. It is like something happening in the great sky. Whatever kind of bird flies through it, the sky doesn't care. That is the mind transmitted from Buddha to us.
Shunryu SuzukiPeople say that practicing Zen is difficult, but there is a misunderstanding as to why. It is not difficult because it is hard to sit in the cross- legged position, or to attain enlightenment. It is difficult because it is hard to keep our mind pure and our practice pure in its fundamental sense.
