Whether you are working alone or in a coven, you might like to start a Book of Shadows.
A Book of shadows may include a record of rituals that have worked well, names of those who need healing, as well as herbal brews and incenses that are especially evocative. In time it is possible that a book of shadows will not only become a personal reference for you to look back on but viable sources of inspiration
Books of Shadows are so-called because early witches kept them secret for fear of persecution.
These books were often burned or buried with witches who died.
You may decide to have two Books of Shadows, one as a permanent record, traditionally copied out by hand, and the other an ongoing working almanac in which you note moon phases for the month.
If you are working in a group that includes someone with a mathematical bent, they can calculate and note here the times of the day at which particular planets and angels hold sway. You can also note the phases of the Moon.
Some covens keep a single main Book of Shadows in a safe place. From this, members – especially new ones – can copy rituals and magical lore in their own smaller Books of Shadows, which can then be handed down in future times to any member of their family who shows an interest in such matters as they reach adulthood.
