勅修百丈清規 1.79

1.79

世祖而下。咸各建寺。謂由佛應身以御天下。化儀既終復歸佛位。在　京官寺。於是設　聖容具佛壇場。月以五祭。設奠展禮如生。而致夫羹牆之思。洪惟　聖化所被。與佛之教流于無垠。而吾徒沐恩波濡　聖澤。可不知所自而思所報効焉。

From Shizu downward, all have established monasteries, considering that the Buddha manifested response bodies to govern all under heaven, and once the forms of transformation ended, they returned to the station of Buddhahood. In official monasteries in the capital, sacred portraits were accordingly installed and Buddha altars provided, offering five sacrifices each month, setting out libations and conducting rituals as if they were living, thus expressing longing like that of seeing the ancestor in the soup and on the wall. We magnanimously contemplate that what the holy transformation has covered flows boundlessly together with the Buddha's teachings; and as we disciples bathe in the waves of imperial kindness and are moistened by holy grace, how could we not know its source and think of repaying it?
