[Treatise:] That there are verbal explanations [is merely the Tathāgata adapting to deluded thoughts with provisional words to guide sentient beings, so that they may] enter into reality—
[Commentary:] "Explication": This harmonizes and explains hidden doubts. "That there are verbal explanations", and so forth: first, it directly harmonizes the hidden doubt. The holy ones fully know that the dharmas are free from nature and are unspeakable characteristics; how could there be words [...] provisional words [...]? Their purport does not lie in the words. "Their purport...", and so forth, determines the holy intention: that there are verbal explanations is intended for returning to the real, not wishing people to pursue names and give rise to thoughts of conceptual discrimination. "Because all...", and so forth, turns back to explain the distinction: because if one pursues names and then gives rise to thoughts, the mind's arising and ceasing will not correspond to the real.
