Theurgy

Theurgy (/ˈθiːɜːrdʒi/; from Greek θεουργία theourgía), also known as divine magic, is one of two major branches of the magical arts, the other being practical magic or thaumaturgy. Theurgy describes the ritual practices associated with the invocation or evocation of the presence of one or more deities (also called "godforms"), especially with the goal of achieving henosis (uniting with the divine) and perfecting oneself.
