Summon the Arch Angels they may arrive just themselves or with their host of lesser angels as well. The four Arch Angels may be summoned for rituals as well as cleansing of scared space. Angels especially Arch Angels do not resemble cherubs one see's on Valentines day cards or Christian Cathedrals, These are being of immense power and divine majesty, They may be invisible or manifest in a variety of shapes forms or images. Regardless their image emanates a light so radiant it is cleansing and purifying and they leave holiness in their wake rather then destruction. Cast a circle with an Athame, wand candle or other tool. Pause at each cardinal point and invoke each guardian, Raphael the east: Michael the south: Gabriel the west: Uriel the north. Make the invocation as complex or as simple as you prefer. Envision each Angels light cleansing and purifying each quarter of your space then thank them with gratitude!!
