Descriptions of prayer are abundant throughout Christian history. “True prayer,” wrote St. Augustine, “is nothing but love.” Prayer should arise from the heart. “Prayer,” said St. John Vianney, “is the inner bath of love into which the soul plunges itself.” ”Everyone of us needs half an hour of prayer each day,” remarked St. Francis de Sales, “except when we are busy—then we need an hour.” Definitions of prayer are important, but insufficient. There is a huge difference between knowing about prayer and praying. On this issue, the Rule of St. Benedict is clear, “If a man wants to pray, let him go and pray.”
