答：惛沈、睡眠行相相似，睡眠復為惛沈，近緣生諸煩惱，故合為蓋。故《瑜伽論》第十一云：無堪任性，名惛沈；惛昧心極略性，名睡眠，由此惛沈生諸煩惱、隨煩惱時，無餘近緣如睡眠者，掉舉、惡作所起處等，設處不等由掉諠動、惡作憂變，相相似故，合立一蓋，即《瑜伽》云：掉舉、惡作俱因親屬尋思國等，昔所經事而起之也。故總結云：由前掉舉與此惡作處所等故合說一蓋，處所不等然如彼相，騰躍諠動。今此亦是憂變之相，是故與彼雜說一蓋。

Answer: Torpor and drowsiness have similar cognitive modes; drowsiness, moreover, serves as an immediate condition for torpor to generate defilements; hence they are combined into one hindrance. Therefore roll 11 of the Yogācārabhūmi states: Unsuitability is called torpor; a state of extreme abbreviation of a dark, confused mind is called drowsiness; because when torpor generates defilements and secondary defilements, there is no other immediate condition like drowsiness. Restlessness and remorse have the same locus of arising; even if their loci are not identical, because restlessness is agitation and remorse is the anxiety of change, their characteristics are similar; hence they are jointly established as one hindrance. That is, the Yogācārabhūmi states: Both restlessness and remorse arise due to directed thought regarding relatives, countries, and so forth, and past experiences. Therefore it summarizes: Because the locus of the former, restlessness, is identical with this remorse, they are jointly explained as one hindrance; though their loci may not be identical, yet like that characteristic of leaping and agitating, this too has the characteristic of anxiety and change; therefore it is explained together with it as one hindrance.
