注維摩詰經 6.139

6.139

什曰：直心中猶有累結，今深入佛法，無雜想也。肇曰：未有得真實慈而雜以淺行者，可名深心。

[Kumāra]jīva says: In the straightforward mind there are still burdensome fetters; now one enters deeply into the Buddha-Dharma and has no mixed thoughts. [Seng]zhao says: There has never been one who attained true loving-kindness who mingled it with shallow practices; this may be called the profound mind.
