佛祖統紀 1.83

1.83

菩薩本行經云。我於無量無邊諸佛所。種諸善根。為轉輪聖王。值無量佛。最初值遇三十億佛。同名釋迦（初阿僧祇始。此佛以其在始故云最初○大論云。如來先世為瓦師。名大光明。時有佛名釋迦文。與弟子俱。到瓦師舍宿。瓦師施草座燈明密漿。便發願言。我於當來作佛。如今佛名）。

The Pusa benxing jing says: 'At the places of immeasurable and boundless Buddhas, I planted various roots of goodness. As a wheel-turning sage king, I met immeasurable Buddhas; initially I met thirty hundred million Buddhas, all identically named Śākya.' (The beginning of the first asaṃkhyeya [kalpa]. Because this Buddha was at the beginning, it is called the initial one. The Dazhidulun says: 'In a previous life, the Tathāgata was a potter named Great Brightness. At that time, there was a Buddha named Śākyamuni who, together with his disciples, went to the potter's house to lodge. The potter offered grass mats, lamps, and honey syrup, and thereupon made the vow, saying: "May I in the future become a Buddha, with a name like this Buddha's today."')
