Since noise is increasing in all directions, the psychology of silence has taken on a special meaning. We are already so adapted to an abundance of screeching sound that we are surprised when stillness suddenly envelops us. Not that this happens very often. We begin to see that the whole question of our relation to the world, both positive and negative, centers in something like silence. So our service to the world might be simply to keep a place where there is no noise, where people can be silent together.
Darkness can be understood to represent emptiness, the complete overcoming of ignorance: the false perception of reality, the illusion of dualism, of anything existing separately. Emptiness, the womb of enlightenment, can be understood symbolically as darkness ... Emptiness is not nothing. Emptiness refers to the radical insight that there is no individually existing, independently arising, separate self. All that is, is in constant flux, rising and falling in relationship to and with something else. Emptiness is the black of starless midnight, imminence, that comes before the pre-dawn of enlightenment, the "clear light", a state of translucence or transparency that is beyond dark and light. This is a radiant black. This is wisdom.
