The quest for this unwearied peace is constant and universal. Probe deeply into the teaching of Buddha, Maimonides, or a Kempis, and you will discover that they base their diverse doctrines on the foundation of a large spiritual serenity. Analyze the prayers of troubled, overborne mankind of all creeds, in every age-and their petitions come down to the irreducible common denominators of daily bread and inward peace. Grown men do not pray for vain trifles. When they lift up their hearts and voices in the valley of tears they ask for strength and courage and understanding.
