After reading the book and listening to the audio CD I finally found the video for this awesome piece!
Letting Go of God is a humorous monologue by Julia Sweeney chronicling her search for God. She begins in the Catholic church, the religion her family raised her in, and takes a Bible study class. What she learns there leads her to new questions, and in search for answers she explores meditation, Buddhism and New Age gurus, then describes what she learned from the sciences and from sharpening her critical thinking skills. She discovers that to accept the truth leads to surprising revelations. She concludes by sharing how this effects her family.
