I've noticed that this card shows up a LOT when I am having dreams of being powerless or feeling trapped. I love it when my cards are that in tune with me.
Third alchemical trump, Sulfur, The Emperor represents Aries - Mars rules and Sol is exulted. Crowley says that the sign is thus a combination of energy in its most material form with the idea of authority.
He is the masculine life force, dynamic, authoritative and full of strong leadership. He is less emotional than his Empress - this energy is perfect for standing strong when feeling vulnerable. Stand strong in your power and trust yourself.
