According to scientific knowledge and observations in the real world, there is no evidence that Taoist priests or others can use supernatural spells. Spells usually refer to the use of supernatural forces, such as transformation, flight, control elements and so on. However, scientific research and experiments have proved that these supernatural abilities do not exist in the real world. People's ability is limited by natural laws and biological limitations, and can't go beyond physical and physiological limitations. Therefore, no Taoist can spell.
