論。熏習義者至則有香氣　述曰。次下廣釋熏習之義。於中有二。先總。後別。□□亦二。初喻。後合。此初也。此中衣者。互通喻於真如無明。而言香者是通好惡。隨應亦喻真如無明。互為能所熏成氣故。

Treatise: "As for the meaning of perfuming: [it is like clothing in the world, which originally has no fragrance; yet if a person uses perfume to permeate it,] then it has a fragrant scent."
Exposition: Next below is the extensive explanation of the meaning of perfuming. In this there are two parts: first, general; later, distinct. The [general] also has two parts: first, metaphor; later, application. This is the first part. Here, the "clothing" interchangeably serves as a metaphor for suchness and ignorance; and the mention of "fragrance" applies generally to both good and bad, and accordingly also serves as a metaphor for suchness and ignorance, as each mutually serves as perfumer and perfumed to produce a scent.
