大般涅槃經義記 8.19

8.19

三凡夫被惑喻，「獼猴癡故往手觸」者，五根之中多先以眼視其色也。「觸已粘」者，見生愛也。言「欲脫」者，五根取境互相易代名為欲脫，非欲解脫。觸境皆貪，斯名粘著。「如是五處悉無脫」者，於五根中皆生著也。

Third, the simile of ordinary beings being deluded. "Because of folly, the monkey goes and touches it with its hand": among the five sense faculties, one mostly looks at its form with the eye first. "Having touched it, it is stuck": seeing it, love arises. Speaking of "wishing to be freed": the five faculties grasping objects and alternating with one another is called "wishing to be freed"; it is not wishing for liberation. Touching objects, all are greed—this is called sticking. "Thus in all five places it cannot be freed": attachment arises in all five faculties.
