@medicchristy: The triple goddess symbol is a representation of the 3 different aspects of the Goddess. There is maiden, mother, and crone and the three moon phases of full, waxing, and waning.
Maidens are usually represented by silver or white to reflect her purity. The mother is represented by red to signify giving birth. The crone is represented by dark purple or black to reflect that she is the evening of her life.
These are some of the common attributes of the triple Goddess:
Mother – protection, fertility, growth, sexuality, and motherhood
Maiden – adolescence, beginnings, purity, virginity, childhood, independence
Crone – wisdom, change, old age, transformation, death, rebirth
