《文昌孝经·辨孝章》
从行为辨别孝，千万不能使行为有所偏颇。从时间来辨别孝，千万不要使其孝行有所改变。从伦常之理来辨别孝，千万不要使其孝行错乱。
又说偈曰：辨之以其心，毋使有不安；辨之以其行，毋使有或偏；辨之以其时，毋使有或迁；辨之以其伦，毋使有或闻。
Discern filial piety from your actions, never let your actions be biased. Discern filial piety from time, never let your filial actions change. Discern filial piety from the reason of constant human relationships, never let your filial actions be disordered.
