As has been mentioned already, “Contemplation” is not something we do, but rather, what God does within us.
“Contemplative Prayer,” is how we begin to open ourselves to God’s grace, who leads us into contemplation.
A formula for Contemplative prayer, which goes back to the Desert Fathers of the 4th Century, of which St. John Cassian wrote about in his experiences with Abba Isaac, who gave conferences on prayer, can be used.
The prayer, “O God come to my assistance, O Lord, make haste to help me,” is used for maintaining reflection on God, in times of meditation, or throughout the day. During meditation, it is said quietly and interiorly, and repeated until the soul is drawn to the center, where God dwells.(See St. John of the Cross, the Living Flame of Love.) Whenever the soul becomes aware that their thoughts have wondered off, they just return to the prayer, gently.
The purpose is to maintain our focus on the presence of God dwelling within us. It is in His presence, that we open ourselves to Him and allow Him, to transform us. It is a resting in God’s presence.
For those who use it, the prayer becomes so much a part of you, that you’ll find yourself praying it throughout the day, on a daily basis. Thus, “pray without ceasing,” is understood.
Also, as you can see, the prayer is from Scripture, but it is also the opening prayer for Evening Prayer in the Liturgy of the Hours.
The Eastern Church also used the “Jesus Prayer,” in the same way. Lord Jesus Christ, Son of God, have mercy on me a sinner." This prayer was said on the Rosary Beads.
However, as in both prayers, its not the words, but rather, returning the focus of our intention on the presence of God, who dwells within. God brings us to full contemplation, not the prayer.
In all, the only path to Contemplation, is to pray. Without prayer, its like trying to win a lottery without purchasing a ticket.
Contemplative Prayer, is the ticket, to open yourself up to Contemplation.
In Christ Jesus
