The word "nine characters" originated from Bao Puzi written by Ge Hong in the Eastern Jin Dynasty. It reads: "I wish you: those who are facing the chaos of war are marching forward in groups, so you should always pay attention to them and do everything well." This means that all evil can be eradicated by reciting these nine words. Tantric Buddhism was influenced by Taoism in China (using the talisman method), but when copying these nine characters, it mistakenly copied "front" as "front" or "front", which has been used ever since.

The right hand is wisdom, the left hand is fixed, the fingers of both hands are connected with the inside and outside as meridians, and the qi, pulse and chakra in the body are latitudes, making six achievements.
