True prayer demands…

By our prayer we share the life of God. True prayer demands that we be more passive than active; it requires more silence than words, more adoration than study, more concentration than rushing about, more faith than reason. The highest state of prayer is to be children in the arms of Love: silent, loving, rejoicing.
–Carlo Carretto (1910-1988)

The mind is fixed on God…

There are three kinds of attention that can be brought to vocal prayer: one which attends to the words, lest we say them wrong; another which attends to the sense of the words; and a third which attends to the end of the prayer, namely, God, and to the thing we are praying for. This last kind of attention is most necessary, and even uneducated people are capable of it. Moreover, this attention, whereby the mind is fixed on God, is sometimes so strong that the mind forgets everything else.
–Saint Thomas Aquinas (1225-1274)
