俱舍論記 21.55

21.55

「應知此三至非色無色」者，答。經言不善，故唯在欲。又《正理》云「為顯惛沈、掉舉二種，唯欲界者有立為蓋，故與眠、悔和合而立，眠、悔唯是欲界繫故。為顯眠、悔唯染污者有得蓋名，故與惛沈、掉舉二種和合而立，惛、掉唯是染污性故。疑准前四在欲可知。

"It should be known that these three ... not in the form or formless realms": this is the answer. The sūtra states that they are unwholesome, so they exist only in the desire realm. Furthermore, the Nyāyānusāra states: "In order to show that styāna and auddhatya are established as hindrances only when they belong to the desire realm, they are established in combination with drowsiness and remorse, because drowsiness and remorse are bound only to the desire realm. In order to show that drowsiness and remorse obtain the name of hindrances only when they are defiled, they are established in combination with styāna and auddhatya, because styāna and auddhatya are exclusively defiled by nature." Doubt, by analogy with the previous four, is understood to exist in the desire realm.
