大般涅槃經集解 36.29

36.29

案寶亮曰：此云論義經。夫理相幽微，若不假以往復，則於義不彰，故取論議之事別為一部也。然此十二盡有文理，如火宅一偈，若脩多羅往取，則舉體是法本也；若以偈頌往擬，便是祇夜；語之是譬，即譬喻經。如此三義，即是三家文，是為無有有理而無文，但文而無理也。

Baoliang states: Here it is translated as “treatise sūtras.” The characteristics of the principle are subtle and profound; if one does not rely upon reciprocal questioning and refutation, the meaning will not be made manifest; hence the matter of debate is taken separately as a division. Now, these twelve all possess both text and principle. For example, regarding the single verse of the burning house: if approached from the standpoint of sūtra, its entire substance is the root of Dharma; if compared as a versified gāthā, it is geya; if spoken as a metaphor, it is an avadāna sūtra. These three meanings are precisely the texts of the three divisions. Thus there is no principle without text, nor merely text without principle.
