The witches knot symbol is a protective talisman used in modern pagan and witchcraft traditions. It is believed to represent the three aspects of the Goddess (Maiden, Mother, and Crone) and the four elements of Earth, Fire, Water, and Air. The witches knot is often depicted as a simple knot, with intertwined loops and no beginning or end, symbolizing the infinite cycle of life, death, and rebirth. In modern beliefs, it is believed to provide protection and ward off negative energies or spirits.
