注維摩詰經 1.302

1.302

[Seng]zhao says: Among the ninety-six kinds of non-Buddhists, the superior ones can also sever defilements and be born in the formless heavens; yet their way is not true, and they ultimately fall back into the three destinies. The Buddha delivers sentient beings of the three vehicles with the wonderful Dharma of the Four Truths; none who have received it ever fall back into saṃsāra. Therefore it is said: 'Once received, they never regress,' permanently completing the unconditioned, and therefore they are ever quiescent.
