大般涅槃經義記 1.159

1.159

問曰：純陀所建大義今時始立，名字先有，今云何言從義立名，名曰純陀？解云：賢聖所有名字雖是父母生時建立，冥與德會，如維摩詰名無垢稱、如須菩提名曰空生，如是等也。

Question: The great benefit established by Cunda has only now been established, but his name existed beforehand; why does it now say that his name was established based on the meaning, calling him Cunda? Answer: Although the names of worthy and holy ones are established by their parents at the time of birth, they secretly accord with their virtues, just as Vimalakīrti is named Undefiled Fame and Subhūti is named Born from Emptiness, and other such cases.
