You can't not think. But thinking can run you ragged. In this brief video I talk a bit about the avalanche of thoughts that came at me pretty fast and furious the other day, and I invite you to practice drawing the mind down into the heart, bringing your thoughts to rest (even briefly) before Christ within you.
Such a practice moves you toward St. Paul's counsel that we are to bring every thought captive to Christ and that we learn to pray without ceasing.
