Now Consider What Your Master Says, 'Who Art in Heaven'

St. Teresa continues her treatise on the Paternoster (the Our Father):

Now consider what your Master says: 'Who art in heaven.' Do you think it's of little importance to know what heaven is and where you must seek your most sacred Father? Well, I tell you that for wandering minds it is very important not only to believe these truths but to strive to understand them by experience. Doing this is one of the ways of greatly slowing down the mind and recollecting the soul.

- St. Teresa of Avila, The Way of Perfection, 28:1
