俱舍論記 4.231

4.231

「有覆無記至法前後得」者，釋。解第三句。謂唯色界初靜慮中修所斷惑，發有覆無記身、語表色，得亦如前但有俱起。雖有上品煩惱，而亦不能發無表故，勢力微劣，由此定無法前、後得。或雖有上品表業，應知一切有覆無記四蘊有三世得，心望色強、又是能發，故三世得。色望心劣、又是所發，故唯法俱。所以此色唯初定者，欲界有覆無記身、邊二見不能發業，二定已上非尋、伺俱亦不發業。

"Veiled-indeterminate [up to] prior and posterior acquisition of the phenomenon" is the explanation. It explains the third line [of the verse]. This means that only the defilements abandoned by cultivation in the first dhyāna of the form realm generate veiled-indeterminate bodily and vocal informative matter, whose acquisition is also, as before, only simultaneous. Although there are afflictions of superior grade, they cannot generate uninformative matter; hence their power is weak, and because of this they definitely lack acquisition prior to or posterior to the phenomenon. Or, although there are superior informative karmas, it should be known that all four aggregates that are veiled-indeterminate have acquisitions of the three periods of time; in comparison with matter, mind is strong and is the generator, so it has acquisitions of the three periods of time. In comparison with mind, matter is weak and is that which is generated, so its [acquisition] is only simultaneous with the phenomenon. As for why this matter exists only in the first dhyāna: the two views in the desire realm, the view of individuality and extreme views, which are veiled-indeterminate, cannot generate karma; from the second dhyāna upward, not being accompanied by vitarka and vicāra, they also do not generate karma.
