首楞嚴義疏注經 5.203

5.203

摩訶迦葉，云大飲光氏，名畢鉢羅，頭陀上行，眾推無上。紫金光尼，在家時婦，緣起如常。日月燈所便得親近，聞法修行。

Mahākāśyapa is translated as the Great Drinker of Light clan; his name was Pippala. His practice of ascetic virtues (dhūta) was foremost, and the assembly recognized him as unsurpassed. The nun Purple-Golden Light was his wife when he was a householder; their karmic origin is as usual. At the place of Sun Moon Lamp, he was able to draw near, hear the Dharma, and cultivate the practice.
