13.146

「身有孔隙故得相容」者，通。異熟虛疎，身有孔隙，故得相容等流表色。故《婆沙》一百二十二云「然表、無表依身而起，有依一分，如彈指、舉足等一分動轉作善、惡業；有依具分，如禮佛、逐怨等舉身運動作善、惡業。此中隨所依身極微數量，表業亦爾。如表數量，無表亦爾。

"Because the body has interstices, they can accommodate each other": this resolves the objection. Fruition is hollow and sparse; the body has interstices, and therefore can accommodate the informative matter of uniform outflow. Thus the Mahāvibhāṣā, fascicle 122, states: "However, informative and non-informative matter arise relying on the body: some rely on one part, as in snapping the fingers, lifting a foot, and so forth, where movement of one part performs wholesome or unwholesome karma; some rely on all parts, as in prostrating before the Buddha, pursuing an enemy, and so forth, where movement of the entire body performs wholesome or unwholesome karma. Herein, according to the number of subtle atoms of the supporting body, informative karma is also like that; as the quantity of informative matter is, non-informative matter is also like that."
