Teresa of Jesus' Transverberation...

"I saw in the angel's hands a large golden dart and at the end of the iron tip there appeared to be a little fire.  It seemed to me this angel plunged the dart several times into my heart and that it reached deep within me.  When he drew it out, I thought he was carrying off with him the deepest part of me; and he left me all on fire with great love of God."
St. Teresa of Avila
