15.57

言中品者，世間定善及彼無漏能斷中煩惱，上品出世善根斷不煩惱。又諸善法，或由加行力等者，景云：近於此生勤修加行成上品名加行力，或曾多生數串習故成上品名串習力，無始性成名自性力，於三寶等勝田施士用力發生上善名田士用力，依彼離欲清淨身起故成上品名清淨力。

The 'middling grade' refers to mundane stabilized wholesome [factors] and those taintless ones that can abandon middling afflictions; the superior grade refers to supramundane wholesome roots that abandon inferior afflictions. Furthermore, regarding 'all wholesome dharmas, either through the power of application, etc.': Jing says: Diligently cultivating application close to this life to achieve the superior grade is called the power of application; or, having repeatedly practiced through many past lives to achieve the superior grade is called the power of repeated practice; being accomplished by nature from beginningless time is called the power of intrinsic nature; generating superior wholesomeness through exerting effort toward superior fields of merit such as the Three Jewels is called the power of the field and exertion; arising based on that pure body free from desire to achieve the superior grade is called the power of purity.
