Pray in silent devotion…

As far as possible, you should pray in quiet silent devotion. Try to have a favorite topic of prayer, such as a devotion to the passion of Jesus, the Blessed Sacrament, awareness of the divine presence: go directly to Jesus without too much fuss.
–Saint Peter Julian Eymard (1811-1868)

Three simple instructions…

I will give here three very simple instructions:
1. always begin praying with at least a little preparation;
2. do not pray carelessly, but with attention and feeling; and
3. do not go on to ordinary work immediately after prayer.
–Saint Theophan the Recluse (1815-1894)

Prayerful zeal…

However, one does not have to do many prayers. It is better to perform a small number of prayers properly than to hurry through a large number of prayers, because it is difficult to maintain the heat of prayerful zeal when they are performed to excess.
–Saint Theophan the Recluse (1815-1894)
