This year i am waking up on dawn, and going for a walk. I will first make breakfest, give a gift, pray, then walk. I will then do a noon ritual, and go out for daily mundane activities, i will come home, pray again and relax.
Questions: Sometimes you work with deities who are not the ''sabbat kind''. Say your patron is Zeus, and the sun god is apollo.It's okay, take a breath.
I usually ask all deities to come and join me, i thank and ask all gods to aid me in the yule time. But i then say a poem, or do personal magic, asking for the sabbats deity to aid me.
