Jacob Boehme. 
 
John M. Watkins: 1960. Hardcover in a jacket. Octavo. Mild foxing to the top edge of the text block, mild soiling to the fore edge. A few pages within the text block have light underlining in pencil. Unclipped jacket is rubbed, torn, and edge worn. 723 pages. Book and jacket are good. 
 
In this case, you should judge the book by the cover. In the Biblical sense of the word, Boehme is the harvest. Apocalyptic and fleshly, strange and yet speaking to you as if he had no other reader, his works are picnics in which he brings the words and the reader the meaning. If you are serious about mysticism, you need Boehme.
