《晋书·志·第二章》
仁义礼智，以诚信为主，貌言视听，以心为正，所以四星若全部失却常态，镇星就会因此而动。
仁义礼智，以信为主，貌言视德，以心为正，故四星皆失，填乃为之动。
Benevolence, uprightness, propriety, and wisdom, with loyalty as chief;  appearance, speech, vision, and hearing, with the mind as chief;  therefore, if these four stars all lose their normal character, the镇星 is set in motion.
