79.82

疏「雖出諸智，佛智不減；菩薩成佛，佛智不增」者，如山出雲，山亦不減；如谷納雲，谷亦不增。「海中板喻」，即〈十行品〉。

Regarding the commentary's "Although it brings forth all cognitions, the Buddha's cognition does not decrease; when bodhisattvas achieve buddhahood, the Buddha's cognition does not increase": like a mountain bringing forth clouds, the mountain does not decrease; like a valley receiving clouds, the valley does not increase. The "simile of the board in the ocean" is in the "Ten Practices Chapter".
