The Bat, in the western culture, is usually seen as a symbol of the night and the forbidden nature. In the Mesoamerican mythology, the bat is part of the mysterious world related to warriors.
The pentacle symbolizes the human body. It represents the human as the potential master of nature, light, air, wind, fire and water; which are controlled by him. In esotericism, it is known as the White Pentagram, and it is a basic protection symbol; a shield that returns evil wishes and curses to its origin. When practicing white magic, it gives protection against dangerous spells.
