Theurgy is the science that puts humans in contact with the Divine and allows us to rely on superior forces in order to advance on the path toward our Real Being. This knowledge is vital for those of us who yearn to return to our inner castle. In this work, V.M. Samael Aun Weor delivers us that knowledge with the Conjuration of the Seven, a very powerful and indispensable tool to protect ourselves from the tenebrous forces that attack the aspirant to the supreme wisdom. And he conveys his vast experience in the world of esotericism, as fantastic as it is real, as only someone who is fully awaken can do.
