Today's card is all about power.
The Emperor hints at how you run your world. Do you seek power over a situation or person, or do you seek to empower others? The emperor tells you how powerfully your ego impacts your life.
The ego is not usually your best friend. The ego is a collection of the habits of behavior you learned as you grew up. What actions might have been appropriate to you as a child may no longer be appropriate as an adult; yet the ego, for its own survival, encourages you to still use many immature weapons of control such as: sulking, the silent treatment, flattery, manipulation, and all the tricks we rely on to get our own way.
Poorly aspected, the emperor in our nature wants to be the "king of the hill", and will use whatever he or she can to achieve that goal. The well-aspected emperor strives to empower others, knowing that, ultimately, what best serves all is what best serves oneself.
There is a high level of trust in this point of view. Remembering this truth helps one relax into one's life, let go of the struggle and negative patterns of behaviour, and know that all is well.
That's true power.
