Summary: Around us, it seems that oral prayer is declining, if not falling into disrepute. However, with passion, we turn to human inner life. There is a growing interest in various methods of gathering and contemplation. This aspect of today's search for prayer was always present to us while writing.

The Holy Spirit within us continues to work in the same way. The Author. Authors: Louf, André; Balthasar, Hans U von (Trans.).
