三彌勒經疏 1.172

1.172

經曰「是時梵摩大長者」以下，第四大臣眾。三結者，一身見、二戒取、三疑。約實永斷三界見惑。而此三結障道增勝故偏說，身見不樂解脫，戒取執著耶道，疑不進修故。盡苦際者，表得七生邊際故。《阿含經》云「今此眾中最小比丘，皆見道迹不趣惡道。極七生往反，必盡苦際」也。

From the sūtra's words 'At that time the great elder Brahmāyu' onward, this is the fourth, the ministers' assembly. The 'three fetters' are: first, the view of personal identity; second, attachment to precepts and observances; third, doubt. In reality, they permanently sever the view-delusions of the three realms. However, because these three fetters obstruct the path most prominently, they are specifically spoken of: the view of personal identity leads to no delight in liberation; attachment to precepts and observances clings to false paths; and doubt prevents advancement in practice. Regarding 'reaching the end of the limit of suffering': this signifies reaching the boundary of seven rebirths. The Āgama says: 'The very least monk in this assembly has seen the traces of the path and will not go to the miserable realms. At most wandering back and forth for seven births, he will certainly reach the end of the limit of suffering.'
