三、料簡善惡相現為障不同：或非障而障、障而非障、障非障俱障、障非障俱不障。非障而障者：若人先發善相，當時歡喜，後起愛慢，輕忽於他；恃此證相作貢高本，漸染名利，過患轉生；心退法壞，捨戒還俗，無惡不造。豈非初因不障之善，後致大障之惡耶？障而非障者：如先發惡相，慚愧怖畏，勤懺此惡，斷相續心永不起罪；勤行眾善，至辦大事。豈非初因於障，後致不障耶？俱障、俱不障，例可知（云云）。若非障而障者：此是善將滅而相現，此善滅表惡生。若障非障者：此是惡將滅而相現，此惡表善生。若障不障俱不障者：此相表善不滅、惡不生。若障不障俱障者：此表惡不滅、善不生。此約初善為語，謂善不障、惡為障，如上分別。

Third, discriminating how the manifestation of wholesome and unwholesome signs differs in being an obstacle: it may be non-obstacle yet an obstacle, an obstacle yet non-obstacle, both obstacle and non-obstacle being an obstacle, or both obstacle and non-obstacle not being an obstacle. As for non-obstacle yet an obstacle: if a person first manifests wholesome signs, at that time they rejoice, but later give rise to attachment and arrogance, looking down on others; relying on these verified signs as a basis for haughtiness, they gradually become tainted by fame and profit, and faults and afflictions multiply; their mind regresses and the Dharma is ruined, they abandon the precepts and return to lay life, committing every unwholesome deed. How could this not be that an unwholesome great obstacle is subsequently brought about due initially to a wholesome non-obstacle? As for an obstacle yet non-obstacle: like one who first manifests unwholesome signs, feeling shame and dread, diligently repents this unwholesome karma, cuts off the continuous mind so that sin never arises again, and diligently practices all wholesome deeds until accomplishing the great matter. How could this not be that a non-obstacle is subsequently brought about due initially to an obstacle? Both being an obstacle and both not being an obstacle can be understood by analogy (and so forth). If it is non-obstacle yet an obstacle: this is a sign manifesting when the wholesome is about to perish, the perishing of this wholesome indicating the arising of the unwholesome. If it is an obstacle yet non-obstacle: this is a sign manifesting when the unwholesome is about to perish, this unwholesome indicating the arising of the wholesome. If both obstacle and non-obstacle are not an obstacle: this sign indicates that the wholesome does not perish and the unwholesome does not arise. If both obstacle and non-obstacle are an obstacle: this indicates that the unwholesome does not perish and the wholesome does not arise. This is spoken with respect to the initial wholesome, meaning the wholesome is not an obstacle and the unwholesome is an obstacle, differentiated as above.
