瑜伽論記 5.238

5.238

基云：於過去世異熟增上果名已生，等流果名已等生，等是相似義故，住現在生名若生，住未來名若起，覆障所礙謂黑闇等者，此有三種，一黑暗謂色暗，二無明暗癡故迷境，三不澄清色暗謂壁障等，若瑠璃等名澄清色則非覆障，雖隔可見。

Ji says: In past lifetimes, the fruit of maturation (vipākaphala) and the fruit of dominance (adhipatiphala) are called "already arisen"; the fruit that accords with its cause (niṣyandaphala) is called "already equally arisen," because "equal" (sama) means similarity. Abiding in the present and arising is called "whether about to arise"; abiding in the future is called "whether occurring." Regarding "hindered by obstruction, that is, darkness and the like": there are three kinds: first, darkness, which is dark form; second, the darkness of ignorance, which confuses objects due to delusion; third, unclarified dark form, that is, walls and screens. If it is clear and transparent form, such as lapis lazuli, it is not an obstruction; though separated, it can still be seen.
