維摩經玄疏 4.19

4.19

三、明十行者，即此十住真心，一心具一切行，念念自然進趣，流入平等法界海，破十品無明，證十品智斷，一切諸行、諸波羅蜜自然增長，出生自行化他功德與虛空法界等，故名十行也。

Third, clarifying the ten practices: based on this true mind of the ten abodes, a single mind is endowed with all practices, and thought after thought naturally advances, flowing into the ocean of the equanimous dharma-realm, breaking through ten grades of ignorance, realizing ten grades of wisdom and severance, with all practices and all pāramitās naturally increasing and generating merits of self-practice and transforming others equal to empty space and the dharma-realm; hence they are called the ten practices.
