阿彌陀經通贊疏 1.68

1.68

梵云孫達羅難陀，此云艶喜，孫陀羅訛也。艶是妻號，色美端嚴無比名艶；喜是自名，擇牧牛難陀，故言艶喜，艶之喜故。是佛親弟，身長一丈五尺二寸。佛化難陀令求出離，慕戀妻美，種種方便示之苦樂等，方肯出家已成聖果。此尊者，世尊華萼慶喜雁行戀美色於王宮，示惡因於地獄，從茲惶怖方肯迴心，知貪欲是招苦之源，悟好色是受殃之本，捨榮棄俗剃髮披緇，故云離欲也。

In Sanskrit he is called Sundarananda, which is translated as "Handsome Joy." "Sundara" is corrupt. "Sundara" was the name of his wife, so called because her beauty and dignity were peerless; "Nanda" was his own name. In order to distinguish him from Cowherd Nanda, he was called Sundarananda, meaning "Sundara's Nanda." He was the Buddha's biological younger [half-]brother, fifteen feet and two inches tall. The Buddha converted Nanda to seek liberation, but he was infatuated with his wife's beauty. Only after [the Buddha] displayed various skillful means showing suffering, bliss, and so forth, did he become willing to leave home, and he has already attained the holy fruit. For this venerable one, the World-Honoured One's brotherly kin, flying in the rank of wild geese, longed for feminine beauty in the royal palace; [the Buddha] displayed evil causes in hell, and only after being terrified did he turn his mind, knowing that sensual craving is the source of suffering and understanding that infatuation with beauty is the root of misfortune. Forsaking glory and abandoning the secular life, he shaved his hair and donned monk's robes; hence it is called "abandoning desire."
