首楞嚴義疏注經 5.313

5.313

富樓那，云滿。彌多羅，云慈。尼，女聲。得四辯才，曠劫便有，非獨今日。苦空實相即權實法也，內祕外現成就眾生，累劫如是。

Pūrṇa means 'full'. Maitrī means 'kindness'. Putra is a female patronymic ('son of'). Attaining the four unhindered eloquences was already present kalpas without beginning ago, not just today. Suffering, emptiness, and the real mark are the expedient and real teachings; inwardly secret and outwardly manifest to bring sentient beings to completion, it has been like this for repeated kalpas.
