27.244

佛言。生長壽天不知植福。福盡命終還墮惡道。而今不以世樂自娛迴以供養。五自慶也。

The Buddha said that those born among the long-lived devas do not know how to plant blessings, and when their blessings are exhausted and their lives end, they fall back into the evil destinies; yet now we do not amuse ourselves with worldly pleasures but turn them into offerings: this is the fifth rejoicing in oneself.
