Since time without beginning, the nature of Awakened Mind and Emptiness has consisted of the same, absolute non-duality of no birth or death, no existence or non-existence, no purity or impurity, no movement or stillness, no young or old, no inside or outside, no shape and form, no sound and color. Neither striving nor searching, one should not use intellect to understand nor words to express Awakened Mind. One should not think that it is a place or things, name or form. One should not think that it is a place or things, name or form. Only then is it realized that all Buddhas, Bodhisattvas and sentient beings possess the same natural state of great Nirvana.
