維摩經玄疏 3.79

3.79

The various treatises follow the sūtras and can be known by analogy. The verse of the *Mūlamadhyamakakārikā* says: "Whatever dharma arises from causes and conditions, that I explain as emptiness"—this expresses the true truth; "It is also called nominal designation"—this expresses the conventional truth; "It is also called the meaning of the Middle Way"—this expresses the ultimate truth of the Middle Way. This verse explains the Mahāyāna, expressing the principle of the three truths. As for the two chapters below clarifying that the śrāvaka sūtras enter into the ultimate truth, this separately explains the Tripiṭaka teaching, expressing the principle of the two truths.
