Crowley - 10 Wheel of Fortune
Type of spiritual experience
Crowley has the wheel with ten spokes, but I do not know why. Ten represents perfection and being on the wheel of life does not get you to perfection, you have to leave it and go to the hub, the objective is to get off it!
He clearly had some symbolism in mind, but I have no idea what it was.
All other Tarots use eight spokes or four spokes.
