the Book of Psalms: Prayer of Examen

as I continue my consideration on the Psalms (http://project05952381.blogspot.com/2010/12/book-of-psalms-psalter.html)... the Prayer of Examen, based on Psalm 139:23-24

"Search me, O God, and know my heart; test me and know my thoughts.
See if there is any wickedness in me, and lead me in the way everlasting."
