My friend who is Catholic tells me that he does adoration, where he prays on his knees for an hour. He showed me his rosary, and he uses the beads to contemplate the life of Jesus. He said that if he prayed the entire rosary, it would take about an hour, and he would think about Jesus and his mission. He said that using the posture of kneeling, saying the words of the prayers quietly, and thinking about what Jesus did and how it relates to us was a way to pray with your whole being. He said that often the hour would pass very quickly.
