“Prayer is the life of the new heart. It ought to animate us at every moment….But we cannot pray "at all times" if we do not pray at specific times, consciously willing it These are the special times of Christian prayer, both in intensity and duration.”
Catechism of the Catholic Church # 2697
“There are as many and varied methods of meditation as there are spiritual masters. Christians owe it to themselves to develop the desire to meditate regularly, lest they come to resemble the three first kinds of soil in the parable of the sower. But a method is only a guide; the important thing is to advance, with the Holy Spirit, along the one way of prayer: Christ Jesus.”
Catechism of the Catholic Church # 2707
“Meditation engages thought, imagination, emotion, and desire. This mobilization of faculties is necessary in order to deepen our convictions of faith, prompt the conversion of our heart, and strengthen our will to follow Christ. Christian prayer tries above all to meditate on the mysteries of Christ, as in lectio divina or the rosary. This form of prayerful reflection is of great value, but Christian prayer should go further: to the knowledge of the love of the Lord Jesus, to union with him.”
