Isis is the supreme goddess of the Egyptian tradition, patron of motherhood, mistress of magic. In ancient Egypt, this day was celebrated as the Advent of Isis. Worshippers would gather together to celebrate Isis' return from Phoenicia with the Ark of Osiris.
Celebrate and honor this sacred festival of Isis by creating a small altar in her honor. To do so, gather a white candle, an image of Isis, and any pearl or moonstone jewelry you fancy. Burn lotus, jasmine, or myrrh incense. When the altar space is prepared to your liking, take a moment to breathe and be present in the space. Invite Isis to join your space and spend some time in meditation in prayer with her. Ask her to bless the jewelry you brought.
