Divine Eros: Hymns of St. Symeon, the New Theologian

St Symeon was dubbed a theologian (such a rare designation) for a reason! This book sat on my shelf for a couple of years before reading. The time had to be right in order to delve into the deep hymns that read so much differently than prose. These hymns are like a long stream of consciousness outpouring where you travel downstream stopping here and there for moments of "lectio divina" meditation when a passage really sinks into the nous. St Symeon is a great expounder of what theosis is. The beginning of the book also has a condensed biography of the saint that is edifying. I would recommend the full biography as well. His ascetical works are really good and are written in prose making them a bit more accessible if you find the poetry of the hymns harder to approach.
