This mind, through endless kalpas without beginning, has never varied. It has never lived or died, appeared or disappeared, increased or decreased. It’s not pure or impure, good or evil, past or future. It’s not true or false. It’s not male or female. It doesn’t appear as a monk or a layman, an elder or a novice, a sage or a fool, a buddha or a mortal. It strives for no realization and suffers no karma. It has no strength or form. It’s like space. You can’t possess it and you can’t lose it. Its movements can’t be blocked by mountains, rivers, or rock walls… No karma can restrain this real body. But this mind is subtle and hard to see. It’s not the same as the sensual mind. Everyone wants to see this mind, and those who move their hands and feet by its light are as many as the grains of sand along the Ganges, but when you ask them, they can’t explain it. It’s theirs to use. Why don’t they see it?
… Only the wise know this mind, this mind called dharma-nature, this mind called liberation. Neither life nor death can restrain this mind. Nothing can. It’s also called the Unstoppable Tathagata, the Incomprehensible, the Sacred Self, the Immortal, the Great Sage. Its names vary but not its essence.
