Silence frees us from the need to control others … A frantic stream of words flows from us in an attempt to straighten others out. We want so desperately for them to agree with us, to see things our way. We evaluate people, judge people, condemn people. We devour people with our words. Silence is one of the deepest Disciplines of the Spirit simply because it puts the stopper on that.
~Richard Foster, Freedom of Simplicity (as quoted on the Sojourners blog)
