The Ankh is the supreme symbol of life. The Ankh is closely associated with the Goddess Isis, the Great Mother. It's origins are unknown, however theory states that it may be symbolic of the union of man and woman, or simply a derivative of an African fetish doll carried to promote fertility. Often it is misunderstood as a symbol of devil worship as is the pentagram.
The Eye of Horus has been associated with magnetism, since iron was sacred to Horus. To possess the Eye of Horus was to attract positive energy, and keep away evil. It is also associated with initiation. Looking at the duality of Horus, the "child" is the initiate, young and naive. They are "blind" to danger. As the child matures, so does their spirituality. To truly possess the Eye of Horus, one must balance creation and destruction, matter and spirit, life and death.
The Scarab is a symbol of luck and protection. The "dung beetle" was considered sacred to the Egyptians. It was thought that this beetle's actions were a metaphor for the rolling of the sun across the sky. The dung beetle deposits its eggs in a ball of mud or dung and rolls it along the ground. Scarabs were placed over the heart of a mummy to protect its soul in the afterlife.
