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.
True communication depends upon our being straightforward with one another... But the best way to communicate may be just to sit without saying anything.
Only when you understand people, they may understand you. So even though you do not say anything, if you understand people there is some communication.
