注大乘入楞伽經 8.56

8.56

言七地菩薩善觀心識妄想，斷我我所生滅自共相，無礙辨才善巧決定；雖未能滅心識流注，已於三昧而得自在，漸入諸地，具足菩薩菩提分法。言四無礙辨者，謂法、義、詞及以樂說，義如別釋。

This says that a bodhisattva of the seventh stage is skilled at observing the false discrimination of the mind and consciousness, severs the individual and shared characteristics of the arising and ceasing of the ātman and ātmīya, and has unhindered eloquence that is skillful and decisive. Although they have not yet extinguished the flow of the mind and consciousness, they have already attained mastery in samādhi, gradually entering the various stages and completing the bodhisattva's bodhi-pakṣa dharmas. As for the four unhindered eloquences, they are those of Dharma, meaning, phrasing, and delight in speech, the meanings of which are as explained separately.
