Earth is our home ... the largest living creature in our solar system. The land, the water, the air, and all the things that live on and in them form a gigantic community, an enormous cell. Here fungi, eagles, toads, worms, grasses, mosquitoes, ferns, people, dolphins, spiders, oak trees, and lions — up to ten million separately distinguishable forms of life or species — share Earth's environments. Whatever happens to one part, for good or ill, ultimately affects us all, the whole Earth: our home of abundant riches and indescribable beauty.
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.
