A dense and complicated work, but with beautiful ideas. A great addition to the line of mystical thinking that dates back to Plato. The alchemical cosmology is hard to follow without a guidebook or prior knowledge, but the meat of his ideas in the middle of the book were fantastic and easy to follow. The importance of silence, contemplation, meditation, letting go of the Ego and self-will could have all come straight from Buddhist or other Eastern traditions, but Boehme brings a Western Lutheran perspective that looks at the same ideas from a different angle.
