In the second, "like an eye, etc.": the meaning is: if cataracts are on the eye, one sees hair-nets; if clinging is in the mind, one sees actual self and dharmas. If properly matching the Dharma to the simile: the cataract symbolizes the seventh consciousness, and the hair-nets and the like symbolize the perceived aspect. Now, stating that the cataract symbolizes the perceived aspect has three meanings: 1. Implicitly matching the seventh consciousness—meaning that if one only took the hair-nets, they would only symbolize what is perceived, leaving the seventh mental consciousness with no ground to be subsumed; thus this implicit matching leaves nothing out. 2. Mutual reciprocal implication—since the simile above cites the active agent while the Dharma speaks of the object, it naturally implies the other, subsuming the remainder. 3. Displaying that the hairs and moon have no real essence—although the intention lies in the object, it now instead cites the agent to display that what arises from the agent is well known to lack essence.
