Thor is one of the most famous deities in the Norse Pantheon, and for those who do spiritual work with him, they must have two things in mind. Thor prefers to work with male bearded spiritual-workers and he loves the color red, any kind of clothing that you may have with that color is fine.
Thor is the tipical warrior god, sturdy, stalwart, stoic but very kind and friendly, faithful to friends and the bonds he creates with those who work with him.
Nowadays isn’t hard to find a symbol that represents him, Thor’s Hammer, it is actually very easy to get and you should wear one when doing spiritual work with him, or use a real hammer as a as a symbolic token.
Thor also likes beer, it is actually his favorite alcoholic beverage, but for him the most important thing is to have someone to drink with, as I have mention it before, he is a god that likes to creat friendships and maintain them. He shows you the importance of friendship, not just the merrymaking, but the bond between friends, a brotherhood kind of connection, always being there for a friend when help is needed, being faithfull to them.
