注維摩詰經 5.276

5.276

什曰：生死可厭而能不厭，善處嶮難故名方便也。肇曰：大乘四非常觀即平等真觀，故名為慧。以平等心而處世不倦，故名方便。慰諭之說，即其事也。

[Kumāra]jīva says: "Though saṃsāra is wearying, to be able not to weary of it and skillfully dwell in perils and hardships is called upāya." [Seng]zhao says: "The Mahāyāna's contemplation of the four non-constants is precisely the equanimous, true contemplation; therefore it is called wisdom. With an equanimous mind to dwell in the world without weariness is called upāya. The words of consolation are precisely this matter."
