To study angels is to shed light on ourselves, especially those aspects of ourselves that have been put down in our secularized civilizations, our secularized educational systems, and even our secularized worship system. By secularization, I mean anything that sucks the awe out of things.
You can visualize God's light each day and send it to someone who needs help. Your divine nature can reach out and touch the divine nature of another. Within you is the light of the world, it is to be shared with the world. One way of prayer is to visualize a golden light within you and spread it out, first to those about you and then gradually to the world. Keep on visualizing God's golden light surrounding the earth. If you have a problem, take the matter to God in Silence, visualize it in God's hand. Then leave it, knowing it is in the best possible hands, and turn your attention to other things. Carry with you a constant prayer of gratitude. This will add your love and peace to the world.
