Although we have no actual written communications from the world of emptiness, we have some hints or suggestions about what is going on in that world, and that is, you might say, enlightenment. When you see plum blossoms or hear the sound of a small stone hitting bamboo, that is a letter from the world of emptiness.
Shunryu SuzukiIf you want to study Zen, you should forget all your previous ideas and just practice zazen and see what kind of experience you have in your practice. That is naturalness.
