Patriarch #Bodhidharma said: Without using words, transmitting outside the teachings, pointing directly to the human mind, seeing Buddha nature and becoming Buddha. You are the one who practices, you will understand it, if you are fascinated by these wonderful teachings, that wonderful teaching... you are still occupied by thoughts, still a slave. When you see the pure state of mind together with Buddhas and all sentient beings, no different, you will truly be free from all judgments of all, no matter whose judgment it is.
The reason is because language is to express images. It cannot touch the purity of Buddha nature... if you want to be free.
