From a Homily by St. John Chrysostom
Prayer and converse with God is a supreme good: it is a partnership and union with God. As the eyes of the body are enlightened when they see light, so our spirit, when it is intent on God is illumined by his infinite light. I do not mean the prayer of outward observance but prayer from the heart not confined to fixed times or periods but continuous throughout the day and night.
By which I read the saint to mean not that he thinks poorly of fixed times of prayer, but that prayer of the heart, which involves the whole person is the supreme good to which all other prayer and discipline leads.
