律相感通傳 1.25

1.25

「弟子周穆王時，生在初天，本是迦葉佛時天人。為通化故，周時暫現。所問京西高四臺者，其本迦葉佛於此第三會說法度人。至穆王時，文殊、目連來化，穆王從之，即《列子》所謂化人者是也。化人示穆王，高四臺是迦葉佛說法處，因造三會道場。

"In the time of King Mu of the Zhou, this disciple was born in the First Heaven; originally I was a deva from the era of Kāśyapa Buddha. In order to facilitate conversion, I temporarily manifested during the Zhou. Regarding your question about the Gaosi Terrace west of the capital: originally, this was where Kāśyapa Buddha held his third assembly to preach the Dharma and liberate people. Down to the time of King Mu, Mañjuśrī and Maudgalyāyana came to transform [the realm]; King Mu followed them—these were precisely the 'transformed persons' referred to in the Liezi. The transformed persons showed King Mu that the Gaosi Terrace was where Kāśyapa Buddha had preached the Dharma, and so he constructed the Three Assemblies Sanctuary there.
