注維摩詰經 3.223

3.223

什曰：長者子見其毀形麁衣持鉢救命，徒見其所棄之利，而未見其所得。自外而觀可愍之甚，戀昔悲今冀其有利，故問其利也。肇曰：佛不出家，應為金輪王，王四天下。羅睺羅不出家，應為鐵輪王，王一天下。以其所捨不輕、所期必重，故問其利也。生曰：然捨而出家，故當必有勝事耳。竟有何等利於此耶？

[Kumāra]jīva says: The elders' sons saw him marring his appearance, wearing coarse robes, and holding a bowl to survive; they merely saw the benefits he had abandoned, but did not yet see what he had attained. Viewed from the outside, it was extremely pitiable; yearning for the past and grieving for the present, they hoped that there was some benefit, and therefore asked about its benefit. [Seng]zhao says: If the Buddha had not gone forth, he would have been a golden-wheel king ruling the four continents. If Rāhula had not gone forth, he would have been an iron-wheel king ruling one continent. Because what he renounced was not light, and what he sought was surely weighty, they asked about its benefit. [Dao]sheng says: Since he abandoned it and went forth, there must surely be a superior matter. Ultimately, what benefit is there in this?
