Place your wand on your altar. Imagine a beam of light from above shooting down and charging and and sing the mantra om Mani padme hum. Pick up you wand and hold it like an offering to the east. Say. Archangel Raphael, be present for a gaurd unto this instrument. Imagine a towering winged figure in yellow robes holding a wand before you. Imagine energy flowing from him to your wand. Walk to the south and say. Archangel Michael, be present for a gaurd unto this instrument. Imagine a towering winged figure holding a sword and wearing red robes. Visualize your wand being charged by his energy. Do the same for Gabriel in the west with a cup and blue robes, and Uriel in the north with a pentacle and green robes. Walk to your altar and place it on it. Repeat step one.
