注維摩詰經 6.149

6.149

肇曰：自得法利與眾同歡喜，於彼己俱得法悅謂之喜。生曰：慈悲既以益之，唯喜而無悔也，亦為實喜矣。

[Seng]zhao says: Attaining the benefit of the Dharma oneself and rejoicing together with the multitude, where both others and oneself attain the joy of Dharma—this is called joy. [Dao]sheng says: Since loving-kindness and compassion have already benefited them, there is only joy without regret; this is also genuine joy.
