坐禪三昧經 2.10

2.10

念無量識處，觀空處過，念無量識處功德。習念是法，逮得識處。

Mindful of the sphere of boundless consciousness, he contemplates the faults of the sphere of space and is mindful of the virtues of the sphere of boundless consciousness. Practicing mindfulness of this dharma, he attains the sphere of consciousness.
