Theurgy is the practice of using incantations or charms to summon divine spirits (e.g., a god, angels, etc.) and persuade them to do or reveal something. Angel magic involved rituals such as prayer, fasting, scrying or meditation on holy images to purify the soul and open a channel of communication with angels (1).
