楞伽阿跋多羅寶經註解 1.251

1.251

古註云：「七微塵成一窓塵，七窓塵成一兔毛頭塵，七兔毛頭塵成一羊毛頭塵，七羊毛頭塵成一牛毛頭塵，七牛毛頭塵成一蟣，七蟣成一虱，七虱成一芥，七芥成一大麥。」[麩-夫+廣]即大麥也。

An ancient commentary states: 'Seven subtle dust motes make one window dust mote; seven window dust motes make one hare's hair tip dust particle; seven hare's hair tip dust particles make one sheep's hair tip dust particle; seven sheep's hair tip dust particles make one cow's hair tip dust particle; seven cow's hair tip dust particles make one nit; seven nits make one louse; seven lice make one mustard seed; seven mustard seeds make one grain of barley.' 'Kuang' means barley.
