金剛三昧經論 3.198

3.198

經曰　佛說是經已，爾時阿難及諸菩薩、四部大眾皆大歡喜，心得決定，頂禮佛足，歡喜奉行。

The sūtra states: When the Buddha had finished preaching this sūtra, at that time Ānanda, all the bodhisattvas, and the fourfold assembly were all greatly rejoiced. Their minds attained certainty, and bowing their heads to the Buddha's feet, they joyfully received and practiced it.
