《易传·系辞传下·第十二章》
圣人在做事之前，先谋于贤士，同时又卜筮于鬼神，以谋求吉凶的道理，能如是，虽众人也必能参与这幽明的能事了。
八卦以象告，爻彖以情言，刚柔杂居，而吉凶可见矣。
Before the sages do anything, they first seek out advice from wise men, and at the same time, they divine with ghosts and spirits to seek an understanding of auspiciousness and inauspiciousness. If they can do as such, then even the masses can definitely participate in this mysterious achievement.
