Joseph S. Benner (1872 - 1938) wrote a series of profound spiritual books that are of great benefit for spiritual aspirants who wish to learn how to sit 'at the door of the heart' until it opens and reveals the Kingdom within (also known as 'Awakening' or 'Enlightenment').

In addition to Benner's books, there are also his 'Sun' papers which are excellent.  To get a comprehensive collection of Joseph Benner's books and Sun papers, go to:
