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.
If we are in any way to solve the problems of our day, we must rely on the power of Another, not on our own power. It manifests itself in the human heart as a blind stirring of love, as a living flame of love. Sometimes, this inner fire drives people into solitude where they intercede for humanity and unleash a power which shakes the universe. But the same inner fire drives others into the midst of action with a passionate love for justice and a willingness to die for their convictions.
