2.536

"Lord of the gods, could the king Ratnacchattra of that time have been someone else? He has now realized buddhahood, named Tathāgata Ratnārcis. That king's thousand sons are none other than the thousand buddhas of the Fortunate Kalpa (Bhadrakalpa), beginning with Krakucchanda attaining buddhahood, down to the final Tathāgata, named Ruci. The monk Candracchattra was indeed my own person." / These three [segments] conclude and unite [the past with the present]. Therefore, Kakusandha is also called Krakucchanda, the first of the thousand buddhas of the Fortunate Kalpa; Ruci is the last of the thousand buddhas.
