俱舍論記 27.96

27.96

「又諸無色至由此已遮」者，第二解。又諸無色觀減、止增，五通必依止、觀均地，未至、中間由此已遮，觀增、止減故。又《正理》云「若爾，何緣有漏盡通？樂、苦、遲、速地皆能盡漏故。五是別修殊勝功德，要殊勝地方能發起。」

On the passage beginning with "Furthermore, in all formless [levels]" up to "is thereby excluded": The second explanation. Furthermore, in all formless levels, insight (vipaśyanā) is diminished and calm abiding (śamatha) is increased; the five supernormal knowledges necessarily rely on levels where calm abiding and insight are balanced. The threshold stages (anāgamya) and the intermediate [dhyāna] are thereby excluded, because in them insight is increased and calm abiding is diminished. Furthermore, the Nyāyānusāra states: "If so, for what reason is there the supernormal knowledge of the exhaustion of contaminations? Because all levels—pleasant, painful, sluggish, or swift—are capable of exhausting contaminations. The five [other knowledges] are particularly cultivated sublime qualities, which can only be generated in sublime levels."
