The Long Āgama Sūtra 3.67

3.67

「爾時，梵王告諸天眾曰：『時，典尊大臣豈異人乎？莫造斯觀，今釋迦文佛即其身也。世尊爾時過七日已，出家修道，將諸大眾，遊行諸國，廣弘道化，多所饒益。汝等若於我言有餘疑者，世尊今在耆闍崛山，可往問也，如佛所言，當受持之。』」

“King Brahmā then addressed the host of gods, ‘Was this Prime Minister Govinda a different person? Don’t make this observation. Today, the Buddha Śākyamuni is his body. After seven days, the Bhagavān left home to cultivate the path, leading a great assembly to tour the kingdoms and broadly educate people about the path, benefiting many. If you have any other doubts for me, the Bhagavān is presently staying on Mount Gṛdhrakūṭa. You may go and ask him. Remember well what words the Buddha says.’”
