The mirror is used as a symbol for self-knowledge and reflection in many different religions and literature.
But a mirror symbolises a great deal more than that.
It was traditionally said that a mirror also offers protection against bad external influences, in addition to reflection.
For example, the Pah Kwah mirror is an ancient Chinese protection against bad influences from the outside, which needs to be hung in front of a window or door.
Self- knowledge, reflection, protection against bad influences.
