If you are looking for something to do over Yule, as far as a ritual, Here is something that may be handy.
Write down 13 things you would like to manifest in the new year. These could be anything from relationships, money, health, etc. Write these on separate, small sheets of paper.
Each night of Yule, pick one of your manifestations and burn it while meditating on it to send the intention out to the Universe.
The 13th manifestation is your responsibility. Keep it and work on it throughout the year.
Hope you have a Merry Yule, and Blessed Be
-The Magician
