Yeah, he's called Hegel. Hegel is quite mystical on his own being inspired by Eastern religions and such.
When I took a Kabbalah class (it was one of those free online free unis, I needed some humanities credits) the professor forced us to read some Hegel first in order to better understand non-duality before we even touched any other text. As an extra bonus he'd generally flip out on you if you said the words antithesis, synthesis, thesis around him in regards to Hegel in office hours or glibly typed them in any communications.
