法華論疏 2.446

2.446

This explains the Buddha's knowledge and vision: the four phrases—opening, revealing, awakening to, and entering—all contain the Buddha's knowledge and vision; here it is explained generally in reliance upon the initial section. "What the Tathāgata can realize, because he knows that object with knowledge of reality as it is": "What the Tathāgata can realize" refers to being able to realize the dharmakāya. "Knowledge of reality as it is" presents the knowledge that can realize. "Because he knows that object": that object is precisely the dharmakāya; it presents the dharmakāya that is known.
