This Prayer is Called 'Recollection'

The intellect is recollected much more quickly with this kind of prayer (the Our Father) even though it may be vocal; it is a prayer that brings with it many blessings. This prayer is called "recollection," because the soul collects its faculties together and enters within itself to be with its God. And its divine Master comes more quickly to teach it and give it the prayer of quiet than He would through any other method it might use. For centered there within itself, it can think about the Passion and represent the Son and offer Him to the Father and not tire the intellect by going to look for Him on Mount Calvary or in the garden or at the pillar.

- St. Teresa of Avila, The Way of Perfection, 28:4
