注維摩詰經 3.223

3.223

[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?
