Jacob Boehme 
The Confessions of Jacob Boehme [EPUB ebook] 

‘The Confessions of Jacob Boehme’ will serve as a gentle introduction to Boehme for curious readers. This work was not published as such by Boehme, but compiled by W. Scott Palmer in 1920 from an 18th century translation of his complete works.
Jacob Boehme was a German Christian mystic, who, despite humble origins, wrote encyclopaedic works detailing a visionary universe, densely inhabited by spirits. Like many other mystics, Boehme saw dualities and trinities everywhere. He believed that there were three worlds: the world of Light, the world of Darkness, and the world of Fire. He believed that heaven and hell overlap spatially. The Devil is incapable of communicating with God, because (as we would say today) he in is a parallel universe!
