唯識二十論述記 2.314

2.314

長者答言：我為汝喻，譬如有人性甚愚癡，取一黠婦，婚姻以後，遂便有娠。婦言：兒生應須戲具，語聟預覓，時聟覓得一獼猴子，將還與婦。婦語其聟，汝須浣染舂，方堪為戲具。聟將雇人欲浣染舂，他謂其曰：乃可浣洗，云何染舂？此若是衣，可作三事，獼猴不然，其云何作他為洗之。洗之既訖，置熱汁中，染其獼猴，皮肉時已爛壞，後取舂之，形相都失，亦復不堪為兒戲具。汝法亦爾，既非淨物，唯可浣洗，不可受持，如不可染；不可修行，如不可舂。云何令我受持修學，闍提於是慚恥而去，此指於彼故言返問。然《婆沙》第二十七，亦有此文。

The householder replied: "I shall give you a simile: Suppose a man is exceedingly foolish by nature and takes a clever wife. After marriage, she becomes pregnant. The wife says: 'When the child is born, he will need a plaything.' She tells her husband to seek one in advance. The husband then finds a young monkey and brings it back to his wife. The wife says to her husband: 'You must wash, dye, and pound it; only then will it be fit as a plaything.' The husband takes it to hire someone to wash, dye, and pound it. The other person says to him: 'One can indeed wash it, but how could one dye and pound it? If this were cloth, these three things could be done; a monkey is not like that—how could it be done?' The other washes it for him. After the washing is finished, he places it in boiling broth to dye the monkey; its skin and flesh are immediately rotten and destroyed. When he later takes it to pound it, its form and appearance are entirely lost, and it is no longer fit to be a child's plaything. Your teaching is just like this: since it is not a pure thing, it can only be washed, but cannot be retained and upheld, just as it cannot be dyed; it cannot be practiced, just as it cannot be pounded. How could you have me retain, uphold, and train in it?" Jñātiputra was thereupon ashamed and departed. This refers to that incident; hence it says "counter-questioned". However, chapter twenty-seven of the Mahāvibhāṣā also contains this passage.
