涅槃經遊意 1.191

1.191

今所明涅槃之體，非善非不善，非記非不記，無一定相。善巧方便，無所不是善不善。有時為對不善，如復道是善。故云：諸惡已斷，眾善普會。

Now, what we explain as the essence of nirvāṇa is neither wholesome nor unwholesome, neither neutral nor not neutral, having no fixed characteristic. Through skillful means, there is nothing that is not wholesome or unwholesome. At times, to counter what is unwholesome, it is spoken of as wholesome. Therefore it is said: all evils are already severed, and all wholesome qualities are universally gathered.
