The blood of Isis, and Menstruation

While we cannot be certain of the original meaning of the symbol, there seems to be a link to blood, power and regeneration.

One of the most important rituals was preparing a ‘drink of immortality’ made from menstrual blood, which is full of healing stem cells, which can actually activate our cellular capacity to regenerate and transport us to endocrine states of rapture.

"The Bible also calls menstrual blood the flower (Leviticus 15:24), precursor of the fruit of the womb (a child). As any flower mysteriously contained its future fruit, so uterine blood was the moon-flower supposed to contain the soul of future generations."

(NOTE FOR MALES: It is equally important for you to understand these truths about your sisters and the Goddess. Also, modern male biochemistry has proven that males have a (perhaps more subtle) monthly cycle as well, so this information is also for you!)

There is magic inherent in the menstrual cycle. Each cycle provides a woman with the opportunity to understand and read the messages her body gives her for any specific healing she needs.

Ordinarily the Annunaki imbibed the Priestesses’ menstrual blood which they believed was full of nutrients and contained an essence that not only lengthened their lives but also brought them to a higher state of consciousness.
During the temple ceremonies, the Priestesses would also bring themselves to arousal, causing the release of fluid emitted from the Skene’s Gland. This fluid is filtered blood plasma, and so is a rich source of hormones.
