You have to experience duality for a long time until you see it's not there. Don't consider dualistic prayer on a lower level. The lower is higher. There are no levels. Any moment you can break through to the underlying unity which is God's gift in Christ. In the end, Praise praises. Thanksgiving gives thanks. Jesus prays. Openness is all.
