This is an exercise to start practicing Hieros Gamos, the union of feminine and masculine polarities into Oneness, within ourselves.
1. Visualize any Divine Feminine and Divine Masculine embodiment (Goddess and God) that you resonate with, for example Astara (Isis) and Ashtar (Osiris), standing with their feet just above your head, the Goddess over the left side of your body, and the God above the right side. Then visualize and feel both them them entering your body, the Goddess into the left half of your body, and the God into the right half. Feel their presence within you for some time.
