The idea is to draw the essence of the lunar goddess into the body of a coven member, usually a priestess or leader. 
This is done by another member who channels lunar energy down through a receptacle such as a chalice or knife. The two stand facing each other in the center of the circle and the group asks the goddess to come down. Once the divine energy enters the tool, it is touched to the head, chest, or abdomen of the priestess. Through her body, the goddess speaks to the group by answering questions, giving instructions, offering blessings, or simply pouring her loving energy into the circle and leading you in a merry spiral dance. After returning the energy to the goddess, the sign of a pentagram may be used as a dismissal.
Witches invoked their Goddess by ‘drawing down the moon,’ a rite dating back to the moon-worshipping Thessaly, centuries before the Christian era.
Thessalian priestesses also prefigured ‘witchcraft’ by laying curses with ‘moon-dew,’ said to be the first menstrual blood of girls gathered during a lunar eclipse.
St. Augustine berated women for dancing ‘impudently and filthily all the day long upon the days of the new moon.'
The phases of the moon are to be compared to the three ages of woman: the new moon representing the young virgin, the full moon representing woman in her full sexual potential and the waning moon representing the wisdom of old age."
