瑜伽論記 4.223

4.223

今說言所愛味淨定已出，能愛之心當言正入，基云：淨定已入過去出於現在，味定在現在故當言正入，清淨靜慮謂有中根利根等煩惱行薄塵行方能修入，不言下根及三毒偏增修得淨定。

it now states that the pure concentration that is savored has already been emerged from, and the mind capable of savoring should be said to be properly entering. Ji says: The pure concentration has already entered the past and emerged from the present; since the savoring concentration is in the present, it should be said to be "properly entering." As for pure dhyāna, only those with medium faculties or sharp faculties, whose afflictions are thin and whose defilements are faint, are able to cultivate and enter it; it does not say that those with inferior faculties or with disproportionately increased three poisons cultivate and attain pure concentration.
