Who knows the eight-character mantra

What you say seems to be the truth of nine words.

From Baidu Encyclopedia: Nine-character mantra, from the Eastern Jin Dynasty Ge Hong's "Bao Puzi's Inner Chapter: Deng Yu", the original text is "Those who fight with soldiers March in array" (the original text is not "Those who fight with soldiers March in array"). When it was introduced into Japan, it was mistakenly copied as "Righteousness, Fight, Fight, Righteousness, Righteousness, Righteousness", which became the mantra that Japan attached great importance to when practicing Taoism.
