基云：謂前卷三十二相中，第二十觀察相法說言，謂有苾芻慇勤懇到善取其相而觀察之，喻況云：住觀於坐坐觀於臥，或在後行觀察前行，故此言謂審觀察三世諸行。於能觀察又復觀察，前四靜慮說為四支，此第五支於前能觀更審觀察，此所觀察即三世行，即在後行觀察前行，是重觀三昧也，或前之四支雖已觀察此更審觀彼三世境，於前能觀察之所觀察更復觀察故。

Ji says: In the thirty-two marks of the preceding fascicle, the twentieth, the mark of contemplation, says in its doctrinal explanation: 'There is a monk who attentively and earnestly grasps its mark well and contemplates it.' The simile says: 'Standing, he contemplates sitting; sitting, he contemplates lying down; or walking behind, he contemplates walking ahead.' Therefore, this phrasing means carefully contemplating the conditioned phenomena of the three periods of time. Contemplating again that which can contemplate: the preceding four dhyānas are described as four factors; this fifth factor further carefully contemplates that which was previously able to contemplate. That which is contemplated is precisely the conditioned phenomena of the three periods of time, which is 'walking behind and contemplating walking ahead'—this is repetitive contemplation samādhi. Alternatively, although the preceding four factors have already contemplated, this further carefully contemplates those objects of the three periods of time, because it contemplates again that which was contemplated by that which could previously contemplate.
