大毘盧遮那成佛經疏 2.53

2.53

第廿四「云何陂池心？謂隨順渴無厭足法」者，譬如陂池，若眾水流入終無厭足。是心亦爾，若名利眷屬等事來集其身，終無厭足，乃至於所學法亦爾。如已得乳糜不務速食，更復渴望餘味。是中少欲知足以為對治。

Twenty-fourth: regarding "What is the pond mind? It means according with the dharma of thirst without insatiability": just as with a pond, though many waters flow into it, it is never satiated. This mind is also like this: if matters such as fame, profit, and retinue gather upon their person, they are never satiated, even extending to the dharmas they study. It is like having already obtained milk-porridge, but not applying oneself to eating it quickly, yet thirsting further for other flavours. Here, few desires and contentment serve as the antidote.
