CCC 2668

The invocation of the holy name of Jesus is the simplest way of praying always. When the holy name is repeated often by a humbly attentive heart, the prayer is not lost by heaping up empty phrases, Cf. Mt 6:7. but holds fast to the word and "brings forth fruit with patience." Cf. Lk 8:15. This prayer is possible "at all times" because it is not one occupation among others but the only occupation: that of loving God, which animates and transfigures every action in Christ Jesus.
