What is “Drawing down the moon”?
 
It’s the name given to special ritual performed at the esbats (see: “What is esbat” and “What is “sabbat”) by the high priestess when it’s full moon, and it’s especially used to embody  the Goddess’ energy or to make use of the energy of the moon in lunar practices. In certain practices a version of this performed by the high priest under the name of “drawing down the sun”. It’s a practice completely different from a standard esbat or practice; reaching to the required visualization and state of consciousness requires focusing of pure will by special gestures and methods.
