分別功德論 5.2

5.2

所以稱難陀比丘端政第一者，諸比丘各各有相：身子有七、目連有五、阿難有二十，獨難陀有三十相。難陀金色、阿難銀色。衣服光曜金鏤履屣，執琉璃鉢入城乞食，其有見者無不欣悅。自捨如來，餘諸弟子無能及者，故稱端政第一。亦云諸根寂靜者，佛將諸弟子至毘舍離柰女精舍。時難陀在外經行，柰女聞佛來心中欣悅，欲設微供即行請佛。於外見難陀經行，愛樂情深，接足為禮以手摩足。雖覩美姿寂無情想，形形相感便失不淨。甘味潤體，體滿則盈，不淨之溢豈由心哉。柰女不達，疑有欲想。佛知其意，告柰女曰：「勿生疑心。難陀却後七日當得羅漢。」以是言之，知心不變易也。

The reason why the monk Nanda is proclaimed foremost in handsome appearance is that the monks each had distinct marks: Śāriputra had seven, Maudgalyāyana had five, Ānanda had twenty, and Nanda alone had thirty marks. Nanda was golden in color, and Ānanda was silver in color. In radiant robes and gold-embroidered shoes, holding a lapis lazuli bowl, he would enter the city to beg for food, and none who saw him were not delighted. Setting aside the Tathāgata, none of the other disciples could match him; therefore he is proclaimed foremost in handsome appearance. It is also said that his faculties were serene. Once the Buddha led the disciples to the mango girl's vihāra in Vaiśālī. At that time, Nanda was walking outside in meditation. Hearing that the Buddha had arrived, the mango girl was delighted in her heart; wishing to provide a humble offering, she went to invite the Buddha. Outside, she saw Nanda walking in meditation, and deep affection arose in her. Touching his feet in veneration, she rubbed his feet with her hands. Although he beheld her beautiful form, he was serene and free of desire, yet because body and form stimulated each other, he had an emission of impurity. Sweet tastes nourish the body; when the body is full, it overflows. How could an overflow of impurity be caused by the mind? The mango girl did not understand and suspected he had lustful thoughts. The Buddha knew her thoughts and told the mango girl: 'Do not harbor doubts. Seven days from now, Nanda will become an arhat.' From this it is known that his mind was unwavering.
