Original text: 若未生起。所应断法。修善法力。了知如病。深心厌坏。了知如痈如箭。障碍无常苦空。及以无我。深心厌坏。名修故知。如是知已。数修习故。无间道生。断诸烦恼。名修故断。烦恼断已。证得解脱。名修故证。如如进趣上地善法。如是如是令其下地已断。诸法转成远分。乃至究竟。名修故远。当知是名八种修业。

Explanation: If the dharmas that should be eliminated have not yet arisen, through the power of cultivating wholesome dharmas, one comes to know that the dharmas to be eliminated are like an illness, and with deep mind one feels disgust and aversion; one comes to know that the dharmas to be eliminated are like an abscess, like a poisoned arrow, obstructing the wisdom of impermanence, suffering, emptiness, and non-self, and thus one's deep mind grows weary of them—this is called "knowing through cultivation." Having thus known the nature of the dharmas to be eliminated, because of repeated and repeated cultivation, the uninterrupted path arises and all afflictions are eliminated—this is called "elimination through cultivation." After the afflictions have been eliminated, one attains liberation—this is called "realization through cultivation." In this way one continually advances toward the wholesome dharmas of higher stages, and in this way causes the afflictions of lower stages to be eliminated, so that the dharmas of lower stages become ever more distant from oneself, until ultimately they are far removed—this is called "distance through cultivation." These should be known as the eight kinds of cultivation activity.
