The Ascendant is the driver. Your Sun is the car you're driving; the AC is how you steer it through the world. The first impression. The handshake. The way you see and the way you're seen, before a word is said.

It's the sign that was climbing the eastern horizon at the exact minute and place you were born. It moves every two hours. Nobody born across town an hour later has yours. This is the most time-sensitive, most personal point in the chart. It sets the whole thing in motion.

The Descendant is the seat across the table. Whatever the AC isn't, the DC is — so you go looking for it in other people. It's not really them. It's the half of you that you meet by meeting someone else.
