注維摩詰經 9.140

9.140

什曰：意存兼濟，故樂遊無畏。肇曰：生死雖苦，大道之所因。菩薩好遊，故想如園觀也。

[Kumāra]jīva says: Because their intention is to save all beings universally, they roam joyfully without fear. [Seng]zhao says: Although saṃsāra is suffering, it is that on which the Great Way depends. Bodhisattvas delight in roaming through it, and thus regard it as a pleasure park.
