釋禪波羅蜜次第法門 2.12

2.12

二、自誓得戒，即迦葉，是本辟支根性，值佛出世，墮聲聞數中。其答佛言：「佛是我師，我是佛弟子。」作是言已，即便發戒。

2. Obtaining the precepts by self-vow: this refers to Kāśyapa. He originally possessed the capacity of a pratyekabuddha, but encountering the Buddha's appearance in the world, he was included in the rank of the śrāvakas. He answered the Buddha, saying, "The Buddha is my teacher; I am the Buddha's disciple." Having spoken these words, he immediately generated the precepts.
