大方廣佛華嚴經疏 40.17

40.17

第四不壞心果。此下二段，亦即攝隨順堅固一切善根迴向。此為進善，後起大行。今初。不壞心者，由障滅行成，若智若悲皆不退壞。文有十句，初總、餘別。別有九種不壞：一信理決定、二行堪調柔、三不怖甚深、四自乘不退、五勝進無息、六泯絕自他、七利生無邊、八上求地智、九巧化眾生。亦可對前十三昧心以明不壞，恐厭繁文。九並堅固，皆云不壞。十皆具足，名悉圓滿。

Fourth, the fruit of the indestructible mind. The two sections below also subsume the dedication that accords with and solidifies all roots of goodness (kuśala-mūla). This serves to advance in good, after which great practice arises. Now, the first: 'indestructible mind' means that because obscurations are eliminated and practice is accomplished, both wisdom and compassion do not regress or deteriorate. The text has ten clauses: the first is general, the rest are specific. Specifically there are nine kinds of indestructibility: 1. being decisive in faith in the noumenon; 2. practice capable of being pliant; 3. not fearing the profound; 4. not regressing from one's own vehicle; 5. superior progress without cessation; 6. obliterating self and other; 7. benefiting sentient beings boundlessly; 8. seeking the wisdom of the stage above; 9. skillfully transforming sentient beings. One may also explain indestructibility by matching them against the preceding ten samādhi minds, but I fear excessive detail. All nine are solid, so all are called 'indestructible'. When all ten are complete, they are called 'all completely fulfilled'.
