Consider now what your Master says next: “Who art in the Heavens.” Do you suppose it matters little what Heaven is and where you must seek your most holy Father? I assure you that for minds which wander it is of great importance not only to have a right belief about this but to try to learn it by experience, for it is one of the best ways of concentrating the mind and effecting recollection in the soul.
– St. Teresa of Avila
