If you give your life as a prayer, you intensify the prayer beyond all measure. To attain inner peace you must actually give your life, not just your possessions. When you at last give your life bringing into alignment your beliefs and the way you live, then, and only then, can you begin to find inner peace.
To learn to meet our needs without continuous violence against one another and our only world would require an immense intellectual and practical effort, requiring the help of every human being perhaps to the end of human time. This would be work worthy of the name "human." It would be fascinating and lovely.
