How often is it recommended to practice Centering Prayer?

In the beginning, it is recommended that you practice Centering Prayer for 20 minutes, twice a day.  Early in the morning is best, before the activities of the day begin and then again in late afternoon or in the evening.  As your practice stabilizes and your relationship with God deepens, you may feel called to longer periods of prayer.  Attending a weekend or multi-day retreat also helps to deepen one’s prayer practice.
