俱舍論疏 4.49

4.49

論「念謂於緣明記不忘」，《正理論》：「於境明記不忘失因，說名為念。」述曰：由念力故，於緣境明記顯了，能為後時不忘失因，非謂但據緣過去境。

On the Śāstra's statement, "Mindfulness means clearly remembering an object without forgetting": the Nyāyānusāra says: "The cause of clearly remembering an object without forgetting it is called mindfulness." Commentary: By the power of mindfulness, one clearly and distinctly remembers an objective field, serving as the cause of not forgetting at a later time; it does not mean taking only past objects as its objective field.
