Samyuktagama (Sanskrit fragments) 684.14

684.14

「復次，如來於過去宿命種種事憶念：『從一生至百千生，從一劫至百千劫。我爾時於彼生如是族、如是姓、如是名、如是食、如是苦樂覺、如是長壽、如是久住、如是壽分齊。我於彼處死、此處生，彼處生、此處死，如是行、如是因、如是方。』宿命所更悉如實知，是名第八如來力。若此力成就，如來、應、等正覺得先佛最勝處智，能轉梵輪，於大眾中師子吼而吼。

“Furthermore, the Tathāgata remembers the events of his past lives: ‘From one birth to a hundred thousand births or from one eon to a hundred thousand eons, I was born there at that point to such a caste, such a clan, with such a name, and such food. Such were the pains and pleasures I felt, such was my life span, such was my duration, and such was the extent of my life. I died there in that place and was born here in this place. Dying there in that place and born here in this place, such were my deeds, such were the causes, and such were the ways.’ He knows all his past lives in this way. This is called the Tathāgata’s eighth power. If someone accomplished this power, it would be the Tathāgata, Arhat, and Completely Awakened One. Before becoming a buddha, he attained the highest abode of knowledge. He turned the Brahma wheel and roared the lion’s roar amid his great assembly.
