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 eradicated have not yet arisen, through the power of cultivating wholesome dharmas, one comes to know that the dharmas which should be eradicated are like an illness, and with deep mind one feels disgust and revulsion toward them; one comes to know that the dharmas which should be eradicated are like an abscess, like a poisoned arrow, obstructing the wisdom of impermanence, suffering, emptiness, and non-self, and thus one develops deep revulsion in the mind — this is called knowing through cultivation. Having thus come to know the nature of the dharmas that should be eradicated, because of repeated and repeated cultivation, the unbroken path arises and eradicates all afflictions — this is called eradication through cultivation. After the afflictions have been eradicated, liberation is attained — this is called realization through cultivation. In this way, one continually advances toward the wholesome dharmas of the higher stage; in this way, one causes the afflictions of the lower stage to be eradicated, and the various dharmas of the lower stage become ever more distant from oneself, until ultimately they are completely left far behind — this is called distancing through cultivation. The above constitutes the eight kinds of cultivation activities.
