釋氏要覽 2.322

2.322

凡釋氏。晨暮祝香禮佛。乃至作一毫善事。皆回向四恩三有者。蓋是廣大心報恩申孝之至也。

Whenever Buddhists offer incense and worship the Buddha morning and evening, or even perform the slightest good deed, they dedicate the merit to the four kindnesses and the three realms of existence; this is truly the utmost expression of a vast mind repaying kindness and manifesting filial piety.
