The silence of meditation is not the silence of a graveyard; it is the silence of a garden growing. There is no deadness in a garden, but in that all-pervading silence an intense activity is going on in the ground which will later take form as buds, blossoms and fruit. So, too, in meditation there is not a blankness, but a rhythmic activity of the Spirit. As the mind exhausts itself the Spirit comes through, and we are in the realm of heaven. True, we are still on earth, our feet are solidly on the ground -- the holy ground of spiritual awareness.
Ask the animals and they will teach you, or the birds of the air and they will tell you; or speak to the earth and it will teach you, or let the fish of the sea inform you. Which of these does not know the hand of God?
