I have high regards for this sage and I consider his writings as the gold standard of what the writings of sages ought to be. Instead of the usual crap you read, he writes about the truth in a simple manner with full of love.

Here are the books

1. With the Adepts: An Adventure Among the Rosicrucians
2. Magic, White and Black
3. In the Pronaos of the Temple of Wisdom
4. The Life of Paracelsus And the Substance of His Teachings
5. The Life And Doctrines of Jacob Boehme the God-taught Philosopher
6. The Life of Jehoshua the Prophet of Nazareth
