Center yourself to God and PRAY night and day "without ceasing." ALL you do, think, or read can be made into prayer. Great music, art, literature, architecture, friendships are, or can be, forms of prayer. What is gained by prayer can never be lost. PRAYER is eternity breathing in time.
Ultimately, we have just one moral duty: to reclaim large areas of peace in ourselves, more and more peace, and to reflect it toward others. And the more peace there is in us, the more peace there will be in our troubled world.
