Drawing Talismans with the Tip of the Tongue
The difference between drawing talismans with the tip of the tongue and with a brush is that the former uses the tongue as a brush to write directly. The reason for using the tip of the tongue is that the tongue is considered to represent the heart, and in the five elements, the heart corresponds to fire. Therefore, talismans drawn with the tip of the tongue can, in certain situations, possess great power and play a strong role in "suppressing and stabilizing formations".

Drawing Talismans with the Sword Finger
This method involves drawing talismans in the air with the sword finger (a specific hand gesture) without any physical medium. Such talismans do not need to be drawn on any object; the key lies in the method and movement essentials, which are subject to strict requirements. The purpose of these talismans is not for long-term defense but to take immediate effect in emergencies or special situations. Thus, the focus is far more on the drawing movements than on the form of the talisman itself. Since there is no need for the talisman to exist permanently, it is sufficient to visualize and "write" it in the air with the finger.

Drawing Talismans with Ritual Tools
This refers to using Taoist ritual tools such as knives, swords, ritual rulers, command tokens, or court wood (a type of wooden instrument). Its methods and requirements are similar to those of drawing talismans in the air with fingers. For example, the talismans passed down in the Zhengyi School of the Celestial Masters often use this method. Taoists believe that tools like knives, swords, ritual rulers, command tokens, and court wood possess the magical power to subdue demons and evil spirits. During certain Taoist ceremonies or rituals, these tools are required to draw talismans, consecrate water, and issue orders, in order to expel evil, subdue demons, and control ghosts.
