俱舍論疏 1.109

1.109

論「如眼與意至得非擇滅」，指事釋也。「如眼與意專一色時」者，眼謂眼根，意謂意識，即是有一分意識取色之時，餘識等法得非擇滅。或即眼識以意名說，或專一青等色時。用時黃等色及四境念念滅者，能緣彼境五識等法住未來世畢竟不生，以彼不能緣過去故，亦不更能緣餘境故。《正理論》云「如眼與意專一色時，於所餘色及一切聲、香、味、觸等，念念滅中緣彼少分意及法處，得非擇滅，以五識身與一分意識身等於已滅境終不能生，緣俱境故。」述曰：一分意識者，如八勝處等，唯緣現境不緣過去，亦所緣定故，得非擇滅。意及法處者，意是諸識，法處者心所及四相等。

On the Śāstra's statement: 'Just as when the eye and the mind [...] attain apratisaṃkhyā-nirodha': this points to an example to explain it. As for 'just as when the eye and the mind are concentrated on a single form': the eye refers to the eye faculty, and the mind refers to the mental consciousness; that is, when a portion of mental consciousness grasps a form, the remaining consciousnesses and other dharmas attain apratisaṃkhyā-nirodha. Or the eye-consciousness is referred to by the name 'mind'; or it is when one is concentrated on a single color such as blue. At the time of its functioning, yellow and other colors as well as the four sense objects perish moment by moment; the five consciousnesses and other dharmas that could take those objects as conditions abide in the future and ultimately never arise, because they cannot take the past as cognitive object, nor can they further take other objects as cognitive object. The Nyāyānusāra says: 'Just as when the eye and the mind are concentrated on a single form, with respect to the remaining forms and all sounds, odors, tastes, and tangible objects, as they perish moment by moment, the mind and dharmāyatana that would grasp a small part of them attain apratisaṃkhyā-nirodha, because the five consciousness-bodies and a portion of the mental consciousness-body can never arise with respect to objects that have already perished, since they take simultaneous objects.' Commentary: A portion of mental consciousness refers to things like the eight abhibhvāyatanas, which take only present objects and do not take the past, and their cognitive objects are fixed; thus they attain apratisaṃkhyā-nirodha. Mind and dharmāyatana: mind refers to the consciousnesses; dharmāyatana refers to caittas, the four characteristics, and so on.
