"Knowing Buddha means nothing else than knowing sentient beings, for the latter ignore that they are potential Buddhas, whereas a Buddha sees no difference between himself and other beings. When sentient beings realize the Essence of Mind, they are Buddhas. If a Buddha is under delusion in his Essence of Mind, he is then an ordinary being. When your mind is crooked or depraved, you are ordinary beings with Buddha-nature latent in you. On the other hand, when you direct your mind to purity and straightforwardness even for one moment, you are a Buddha. Within our mind there is a Buddha, and that Buddha within is the real Buddha. If Buddha is not to be sought within our mind, where shall we find the real Buddha? Doubt not that Buddha is within your mind, apart from which nothing can exist. Since all things or phenomena are the production of our mind, the Sutra says, "When mental activity begins, things come into being; when mental activity ceases, they too cease to exist.""
