David discusses many practical ideas about living in this world and how to apply them in our day-to-day lives. He shares a key ACIM idea of bringing illusions to truth or darkness to the light. So often we can be tempted to do the opposite and try to manifest a better life here on earth. But the Course is teaching us to give everything to the Holy Spirit; His guidance will lead us home. It is not our responsibility to try and fix anything, all we are asked to do is bring the darkness to the light.
