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.
As we walk on the earth, encouraging a sense of care and kindness, it is as if the earth itself responds — up through the soles of our feet we experience the sustaining nature of the earth... We feel ourselves participating in a calm yet joyous celebration of the earth and the life sustained by the earth.
