大乘義章 5.45

次約三界分別五蓋。通論五蓋悉在欲界，於中細辨，義有通局。瞋眠及悔唯在欲界，貪疑睡掉遍通三界。此雖遍通，於中分取，在欲界者說為五蓋，非上二界。何故如是？《毘婆沙》云「以上二界無不善故。」《成實》釋云「以欲界者，一向障定。上二界者，非全障故（此四門竟）。」

Next, distinguishing the five hindrances according to the three realms. Broadly speaking, the five hindrances are all in the desire realm; analyzing finely within this, their meanings have the pervasive and the restricted. Anger, sleep, and remorse exist only in the desire realm; greed, doubt, torpor, and restlessness pervade the three realms. Although these pervade, taking them selectively, those existing in the desire realm are spoken of as the five hindrances, and not those of the upper two realms. Why is it like this? The Vibhāṣā states: 'Because in the upper two realms there is nothing unwholesome.' The Tattvasiddhi explains: 'Because those in the desire realm exclusively obstruct samādhi, whereas those in the upper two realms do not completely obstruct it (this finishes the fourth gateway).'
