Drawing Down the Moon is a very powerful ritual mostly used in Wiccan practice, but not limited to. It was also thought that this particular ritual dates back to the 2nd Century B.C.E (Before Common Era) where a depiction of two women and the moon was found on a Greek vase.
Take your athame and circumambulate three times deosil while saying,
"The star is bright,oh feeble ancient light,
shine on us tonight,by the Shining one's Might!"
You may then sit down or remain standing, asperse yourself with the consecrated water and then say,
"Great Mother, Great star of life, Cosmic Might, ancient provider,
descend apace, unto me... I ask you...perfect your love, perfect your trust,
your daughter call unto thee. Descend into the body, blest holy since the beginning of time!"
You may either dance a frenzy dance, calling the Great names of the Goddess or sit down and reflect. Soon, there may be a shift of consciousness.
Let the Goddess take hold of you, surrender and She shall impart wisdom unto you.
