At the time of the Full Moon, take your Book of Shadows (one that
hasn't been written in yet) and some incense (pennyroyal, anise or rue) outside.

Under the light of the Full Moon, draw a pentagram on the first page and under this
write the following information: date, time, place, your magical name (and sigil if you have one),
the moon's phase and any other info you feel is important.


Hold the book up to the Moon and say:

"Here as the Full Moon shines upon me,
Bless this Book I've made tonight.
I humbly ask this of thee,
Underneath your most sacred light."
