The Diamond Samadhi Sutra

Wu-Chu Bodhisattva says to the Buddha, “Honored sir,
what kind of benefit transmission can be applied to bring the consciousness of sentient beings into Amalaka?”

The Buddha replies, “Buddhas usually use one enlightenment
to turn the sentient beings’ consciousnesses into Amalaka.

Why so? Buddhas usually transform the sentient beings with one enlightenment,
bringing basic enlightenment to them so that they can understand that all Consciousnesses are empty and without arising.

Why?
This is because the innate nature does not move at all.”
