The pentagram is a five-pointed star sacred to many Pagans and Wiccans, and within this magical symbol you'll find a number of different meanings. Think about the very concept of a star -- it is a source of light, blazing in the darkness. It is something physically very far away from us, and yet how many of us have wished upon one when we saw it up in the sky? The star itself is magical.
Within the pentagram, each of the five points has a meaning. They symbolize the four classical elements -- Earth, Air, Fire and Water -- as well as Spirit, which is sometimes referred to as the fifth element. Each of these aspects is incorporated into this Tarot card layout.
