大般若波羅蜜多經般若理趣分述讚 2.81

2.81

讚曰：此即第五常記平等德。謂諸如來常隨記念若事若處若如若時，有所為作皆隨正念，普於一切所作事業、普於一切方處差別、普於一切所作方便、普於一切時分差別，念無忘失常住正念，名無忘念。恒住捨性者，謂六恒住法。於六根門不憂不喜，但起正捨平等觀境。

The commentary says: This is the fifth [aspect], the virtue of constant mindfulness and sameness. It means that the Tathāgatas constantly follow recollection and mindfulness: whether regarding matter, place, manner, or time, whatever they do is entirely accompanied by right mindfulness. Universally regarding all actions and deeds, universally regarding all distinctions of direction and place, universally regarding all skillful means undertaken, and universally regarding all distinctions of time-periods, mindfulness is never forgotten and they constantly abide in right mindfulness; hence it is called “absence of forgotten mindfulness.” “Constantly abiding in equanimity” refers to the six states of constant abiding: at the six sense-doors, neither sorrowful nor joyful, they only give rise to right equanimity, contemplating objects with sameness.
