金光明經文句記 3.103

3.103

初、引經書示。當念深廣，其猶大海。就此懺悔，名之為浴。萬行皆攝，名用諸水。此喻懺得般若。無始惡業繫屬行人，猶如債主。見業實相，名依投王。業隨觀轉，名返供養。此喻懺得解脫。心性無上，猶如牆頭。初心達性，如草依高。行位雖卑，已能超過七方便頂。此喻懺得法身也。書云，即劉子也。

First, citing sūtras and books to show this. When mindfulness is deep and vast, it is like the great ocean. Repenting within this is called bathing. Subsuming all practices is called using various waters. This illustrates repenting to obtain prajñā. Evil karma from beginningless time is tied to the practitioner, just like a creditor. Seeing the true mark of karma is called relying upon and taking refuge in the king. Karma transforming in accordance with contemplation is called returning to make offerings. This illustrates repenting to obtain liberation. The nature of mind is unsurpassed, just like the top of a wall. The initial mind penetrating the nature is like grass relying on high ground. Though the rank of practice is humble, it has already surpassed the summit of the seven expedients. This illustrates repenting to obtain the Dharma-body. "The book says" refers to the Liuzi.
