A spiritual retreat has several purposes. First, it enables retreatants to distance themselves from the normal pressures, distractions and noise of their life and work to enable the presence of Holy Spirit within and around them to come more into focus. Second, it enables them to have the rest, exercise and regular but moderate food and drink intake necessary to optimise this focus. Third, it provides time, space and silence for persistent reflection and prayer in a rhythm that facilitates growing awareness of the gentle voice of the Spirit. Fourth, when conducted at specialised centres, a retreat offers opportunities for spiritual direction by a spiritual director skilled in discernment of the Spirit.
