By the term ‘Spiritual Exercises’ is meant every method of examination of conscience, of meditation, of contemplation, of vocal and mental prayer, and of other spiritual activities… For just as taking a walk, journeying on foot, and running are bodily exercises, so we call Spiritual Exercises every way of preparing and disposing the soul to rid itself of all inordinate attachments, and, after their removal, of seeking and finding the will of God in the disposition of our life for the salvation of our soul.
–Saint Ignatius of Loyola (1491-1556)
