All Buddhas and ordinary people are just one mind. This mind is beyond all measurements, names, oppositions: this very being is it; as soon as you stir your mind you turn away from it.
Huangbo XiyunThe nature of the Absolute is neither perceptible nor imperceptible; and with phenomena it is just the same. But to one who has discovered his real nature, how can there be anywhere or anything separate from it?... ...Therefore it is said: 'The perception of a phenomenon IS the perception of the Universal Nature, since phenomena and Mind are one and the same.'
