述曰：此下第三，解第四難。於中有二：初正解；後結成。此即初也。「如夢中」言，如先已說。譬如夢中，夢兩交會，境雖無實，而男有損精，女有損血等用。「等」者，等取支分勞倦、出汗等用。夢得錢等，其用則無。境雖無實，其眩翳者，所見髮等，無髮等用，餘見髮等，有髮等用，其理亦成。量云：眩翳非眩翳等所見髮等有用、無用成；許無實境故；如夢失精等。

Commentary: Below is the third [section], explaining the fourth objection. Within it there are two [parts]: first, direct explanation; afterwards, conclusion. This is the first. The words "as in a dream" are as stated previously. For instance, in a dream, when dreaming of sexual intercourse, although the object is unreal, a man has the loss of semen and a woman has the loss of blood and other efficacies. "And so forth" includes efficacies such as bodily fatigue and sweating. In a dream of gaining money and so forth, that efficacy is absent. Although the object is unreal, what is seen by someone with cataracts, such as hairs, lacks the efficacy of hairs and so forth, while what is seen by others as hairs has the efficacy of hairs and so forth; this principle is also established. The inference says: "What is seen by those with cataracts and those without cataracts, such as hairs, is established as having efficacy or lacking efficacy; because it is accepted that there is no real object; like the loss of semen in a dream."
