Samyuktagama (Sanskrit fragments) 285.5

285.5

「我作是念：『何法有故生有？何法緣故生有？』即正思惟，起無間等知，有有故生有，有緣故生有。

“I had this thought, ‘The existence of what causes birth to exist? The condition of what causes birth to exist?’ When I properly considered it, this [true] understanding occurred to me immediately: ‘Birth exists because existence exists. Birth exists because of the condition of existence.’
