瑜伽論記 17.472

17.472

次下隨文解釋。言內等淨念正知捨為自性者，謂二定念正知捨不緣外境，於內門中離沈浮，三法平等令心清淨名內等淨，第四靜慮捨念皆言清淨者，以離尋伺四受及出入息八上煩惱，故名清淨。言第二靜慮由彼自性能有作業者，於第二定中有捨念正知，對除尋伺實有作業，然由當地踊躍心隨煩惱所亂總立內等淨名，第三靜慮已遠離故顯彼自性者，第三定離喜相應隨煩惱，顯彼念慧捨三有其自性。

Next below is the phrase-by-phrase explanation of the text. Where it says 'inner equal purification has mindfulness, correct knowledge, and equanimity as its intrinsic nature': this means that in the second dhyāna, mindfulness, correct knowledge, and equanimity do not take external objects; within the internal sphere, they are free from sinking and floating, and these three dharmas are equal and cause the mind to be pure, hence it is called 'inner equal purification'. In the fourth dhyāna, both equanimity and mindfulness are said to be 'pure' because they are free from the eight higher afflictions of investigation, reflection, the four feelings, and inhalation and exhalation; hence they are called 'pure'. Where it says 'in the second dhyāna, by virtue of its intrinsic nature it is capable of activity': in the second dhyāna, there are equanimity, mindfulness, and correct knowledge, which really perform activities in countering investigation and reflection; however, because they are perturbed by the secondary affliction of the elated mind of that stage, they are collectively given the name 'inner equal purification'. Where it says 'because the third dhyāna has already transcended them, their intrinsic natures are displayed': the third dhyāna is free from secondary afflictions associated with joy, displaying that the three of mindfulness, wisdom, and equanimity have their own intrinsic natures.
