The Long Āgama Sūtra 7.96

7.96

時，婆羅門白迦葉言：「尊者初設月喻，我時已解，所以往返，不時受者，欲見迦葉辯才智慧，生牢固信耳。我今信受，歸依迦葉。」

The priest said to Kāśyapa, “Venerable, I had understood you when we discussed that first parable about the moon. I didn’t accept it at that point because I wanted to witness the eloquence and wisdom of Kāśyapa and solidify my belief. Now, I believe and accept [that there’s another world]. I take refuge in Kāśyapa.”
