Fasting from words, fasting from a volume of speech, being willing to humbly accept the yoke of silence and quietude deprives the tongue of the mastery of our hearts and minds. The tongue is a very useful tool for the art of love and for the art of prayer, but it is also the means by which we afflict others and even our own selves so often. So it must be called into holy obedience.
Unless we are creators, we are not fully alive . . . Remember, the root word of humble and human is the same: humus: earth. We are dust. We are created; it is God who made us and not we ourselves. But we were made to be co-creators with our maker.
