Where do you get telekinesis in Final Fantasy XII?

cast the spell at an object that you can pick up (doesn't work on bodies or live people) and it will glow purple. use RT to push it away, LT to pull it in. if you press RT while holding LT, you will drop the object before the time runs out, and if you press LT while holding RT, you will throw the object powerfully forwards. funny when you do it at people's head, if only the weapons hurt them.
