維摩經玄疏 3.59

3.59

Answer: Now in composing the *Doctrine of the Four Teachings*, it pervasively penetrates the various sūtras; there is a separate large text, and here we briefly summarize its essentials. That it penetrates the text of this sūtra is precisely because this sūtra fully clarifies entering the Way through the four teachings; hence one must know the general meaning. However, the various masters mostly draw from sūtras to explain treatises, leading later students to all consider treatises rich and sūtras poor. Now we draw from sūtras and treatises to open up the meaning of the sūtras, wishing to let future students know that sūtras are rich and treatises poor. Revering what was spoken by the Mahāyāna true Buddha brings immeasurable merit; this is the correct cause for entering the Way. To slight sūtras and value treatises is deeply lamentable.
