Use your compass

"If you would carry on the work of meditation in such a way as it may be done with sweetness, be sure that it be bounded with the Scripture; and let nothing fall within the compass of your meditation, but what falls within the compass of the Scripture."

William Bridge, "The Works and Way of Meditation", 3:154 quoted in God's Battle Plan for the Mind: The Puritan Practice of Biblical Meditation, David Saxton, Reformation Heritage Books, 2015, pg. 18
