>>12294500This guy can explain you the basics, there is a lot of information about his works.
Once you are done with his entry level stuff you can get into his less popular teachings like what he had to say about demons and astrology.
This will give you a good starting point on researching his master: Saint Albertus Magnus. He has a lot to say about esoterism and he has a somewhat different approach to Theology in general.
Once you are don with that I would recommend you the works of Heinrich Kramer, Pico della Mirandola, Marsilio Ficino, Saint Bernardino of Siena and Nicholas Rémy. They will give you a good insight on the more esoteric side of Christianity while still being easily understandable.
