Ekottaragama (Sanskrit fragments) 24.5.36

24.5.36

爾時，世尊便往至優留毘村聚所。爾時，連若河側有迦葉在彼止住，知天文、地理，靡不貫博，算數樹葉皆悉了知，將五百弟子，日日教化。去迦葉不遠有石室，於石室中，有毒龍在彼止住。

The Bhagavān then went to the region of Uruvilvā. Kāśyapa was living near there on the shore of the Nairañjanā River. He knew astronomy and geography, and there was nothing he couldn’t comprehend. He even knew how to calculate the number of leaves in a tree. He led 500 disciples, whom he instructed daily. Not far away from Kāśyapa, there was a cave where a poisonous serpent lived.
