"In her book Christ-Centered Mindfulness , Katherine Thompson goes through the history of Christianity to reclaim a Christian mindfulness practice where the focus is on Christ. Like Stone, Thompson cites many passages from the Bible to support her argument about ancient Christian references to mindfulness. She holds that Christ-centered mindfulness is actually "a form of prayer that dates back hundreds of years."
Christian mindfulness or meditation is based on "contemplative prayer," the silent prayer, in which you seek to focus your mind on God. Such were the exercises of St. Teresa of Avila, St. Ignatius Loyola, and Thomas Merton. Teresa of Avila's The Interior Castle is a detailed contemplation about entering the heart of God."
