《文昌孝经·育子章》
于是万物都得以顺利生长，各得其所。天地赋予形体以成就万物，人秉承性理以成之为人。于是人能够超过万物之上，成为万物之灵，脱离愚笨蠢物。人头顶天，脚立地，俯察于下，仰观于上，得以自然地顺从其本性。人们如果安于现实，不知不觉，就会迷失自己的自然本性。
真君曰：乾为大父，坤为大母，含宏覆载，胞与万有，群类咸遂，各得其所。赋形为物，禀理为人，超物最灵，脱离蠢劫，戴高履厚，俯仰自若，相安不觉，失其真性。
Therefore, all things can grow smoothly, each in its place. Heaven and Earth endow bodies to create all things, and man inherits human nature to become human. Therefore, man can surpass all things and become the spirit of all things, breaking away from ignorance and stupidity. Man has his head towards the sky and feet on the ground, looking down and looking up, so that he can naturally follow his nature. If people are content with reality and do not realize it, they will lose their inherent nature.
