成唯識論演祕 3.126

3.126

答：論言增減名能熏者，二隨有一，即是能熏。若不爾者，見道已去，所生無漏，唯增不減，應不能熏。彼尚能熏，此何不許？

Answer: When the Treatise states that increasing and decreasing is called a perfuming agent, if either one of the two is present, it is indeed a perfuming agent. If this were not so, the untainted [dharmas] produced from the path of seeing onward, which only increase and do not decrease, would not be able to perfume. If even those can perfume, why not grant it here?
