If in your heart you make a manger for his birth, then God will once again become a child on earth. – Angelus Silesius

Take a listen to If in Your Heart and at the end of it you’ll find yourself in a fine place to begin Advent.

Friend, whatever you are, you must not stand still:
One must from one light into the other spill. – Angelus Silesius

Angelus Silesius is the monastic name of Johannes Scheffler. Born into a noble Polish Lutheran family, he received a doctorate in philosophy at the University of Padua and became a physician. As a young man he was drawn to the writings of the German mystic Jacob Boehme. Scheffler’s mysticism didn’t sit well with the dogmatic forms of German Lutheranism of the time and, in 1653, he converted to Catholicism. He took the name Angelus, adding the surname Silesius, meaning “from Silesia.” He published two books of poetry: The Soul’s Spiritual Delight and The Cherubic Pilgrim, and was often engaged in public controversy with both the Lutheran and Catholic churches.

His poetry hinted at a quietest mysticism which asserts that the soul, when it attains deep quiet, can experience God directly — a notion neither institution has been too fond of. Click here for more info and books. Thanks to Ivan M. Granger for the bio.
