瑜伽論記 18.52

18.52

Where it says 'the distinction herein... up to aspiration being of the nature of fruition': Tai says that when cultivated to completion, the nature of fruition is the faculty; when not yet completed in cultivation, the nature of cause is the element (dhātu); just as manifest activity and seed, resolute determination and aspiration both have desire and resolute determination as their nature. However, when first arising at the causal stage it is called resolute determination; later, when arising at the fruition stage, it is called desire-joy.
