Advent's silence reaches us as Love:

At the very heart of our experience, each of us has an intuitive sense of the value of unconditional love. We discover great joy when we can love without reservation, suspending judgments and opening fully to the vivid reality of another's being. Unconditional love has tremendous power, activating a larger energy which connects us with the vastness and profundity of what it is to be human. This energy is the energy of the heart ... This energy is the Love of Christ.

~ from "On Love" by John Welwood
