Continued quotes from one: "We must unite mind and heart in order to learn true mental prayer, in other words, we must pray with our whole inner being, with all our mind and heart. How can God give ear to our prayer if we do not even agree with the words we are saying? And how can we agree with the words when we do not pay attention to their meaning? If we want God to heed our entreaty, we ourselves must be totally present in the words we offer up to Him. It is good for our mind to be enthroned in our heart, and as we offer our thoughts to the Lord, our words will be heart-felt, and therefore pronounced attentively, one by one. I am certain that if we resolve to pray like this, then God will be our teacher.....Prayer is a school, and humility is the key to success in this discipline. "
