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.
Quiet helps us find what we are passionate about. In that quiet, ask what it is you should be doing. Service is spiritual work or, to some, work of reverence. First, you have to uncover what it is you have a reverence for…what it is you love. It may not look like something that is grand or very important, but if you can do a good thing, a small thing on a regular basis, and keep going, it will shine a light. It will draw other light to you.
