Contemplative prayer is a deep and simplified spiritual activity in which the mind and will rest in a unified and simple concentration upon God, turned to Him, intent upon Him and absorbed in His own light, with a simple gaze which is perfect adoration because it silently tells God that we have left everything else and desire even to leave our own selves for His sake, and that He alone is important to us, He alone is our desire and our life, and nothing else can give us any joy.
From Thomas Merton, “New Seeds of Contemplation”
