Prayer begins in us the restoration of the divine image, in all its hiddenness and wonder. It brings us closer to the "region of likeness" and every prayer is an act of letting the old self go. It involves "dying". The grain of wheat falls into the ground and dies. Dead, it is destined to bear much fruit.
Ultimately, I think gardening speaks to a deep-seated desire to experience the real, the essential, the astonishingly possible. To garden is gradually to give up control, to fall literally to one's knees and come into closer and closer contact with the tremendous and often bewildering beauty of the world. Nothing, you find, is at all what you thought it was. Dirt is not dirt, but a teeming mass of microorganisms that turns death back into life.
