瑜伽論記 6.455

6.455

雜心亦云：須陀洹勝者名家家，以進斷惑經生勝彼住果經生名勝。泰云：詳夫人天家西方有二說。難陀論師云：人天二趣若往若來。戒賢論師云：二生家家唯於天上二生往來，三生準此。

The Saṃyuktābhidharmahṛdaya also states: 'The superior stream-enterers are called kulaṃkula,' because their undergoing of rebirths while progressing to sever defilements is superior to undergoing rebirths while resting in the fruit; hence they are called superior. Tai says: 'In examining the human and divine clans, there are two explanations in the Western region. Master Nanda says: "They both go and come between the two destinies of humans and devas." Master Śīlabhadra says: "A kulaṃkula of two rebirths goes and comes only through two rebirths in heaven; those of three rebirths should be understood accordingly."'
