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.
Conversation is the ultimate experience of being in love. It involves self-surrender to the heart of mystery, to an uncomprehended "Who", given in a mystical way. The shift in our attention from all finite loves and hates, whether interpersonal, familial or philanthropic to concern for the Transcendent Other, available in the unmediated experience of love and awe, occurs first in that incarnate meaning that we are. We discover by God's gracious love, we are a meaningful word already spoken, a beloved whose very being is the expression of God's turning toward us. In essence, our conversion toward God is the created effect of divine love. We could not pray if God was not already invested in our hearts and mind.
