6.74

自下第二合通會古今明供多益。先會輪王寶炎佛。是次會千子。賢劫中千佛是也。四已成佛。餘在當來。言四佛者。一鳩留孫。二俱那含牟尼。三迦葉。四釋迦。賢劫者善劫也。淨居天劫初成時見水內有千寶蓮花即知有千佛出。故名為賢劫也。樓至佛此云渧泣。出十地經後會。月蓋釋迦佛是。

From here below, the second part unites the past and present to explain that the offering yields much benefit. First, it identifies the wheel-turning king: he was the Buddha Ratnāgni. Next, it identifies the thousand sons: they are the thousand buddhas in the Auspicious Kalpa. Four have already become buddhas; the rest are in the future. As for the four buddhas, they are: first, Krakucchanda; second, Kanakamuni; third, Kāśyapa; fourth, Śākyamuni. "Auspicious Kalpa" means a good kalpa. When the kalpa was first forming, the Śuddhāvāsa gods saw inside the water a thousand jeweled lotuses, and thus knew that one thousand buddhas would appear; therefore, it is called the Auspicious Kalpa. The Buddha Ruci: here translated as "Tearful Weeping"; he appears later in the Daśabhūmika Sūtra. As for Candracchatra, he was the Buddha Śākyamuni.
