俱舍論疏 4.58

4.58

論「輕安者謂心堪任性」，《正理論》云「正作意轉，身心輕利安適之因。心堪任性，說名輕安。」述曰：正作意轉，明所依位，即如理作意正現起時。能為身心輕利安適之因，舉作用也。心堪任性，指其體也。

The Treatise states: "Pliancy (praśrabdhi) means the serviceability of the mind." The Nyāyānusāra states: "When correct attention operates, it is the cause of lightness, agility, peace, and comfort of body and mind. The serviceability of the mind is called pliancy." The Commentary explains: 'When correct attention operates' clarifies the state of its basis, which is the time when wise attention is directly occurring. 'Being the cause of lightness, agility, peace, and comfort of body and mind' indicates its function. 'The serviceability of the mind' points to its intrinsic nature.
