The window is the absence of the wall, and it gives air and light because it is empty. Be empty of all mental content, of all imagination and effort, and the very absence of obstacles will cause reality to rush in.
Still lie the sheltering snows, undimmed and white; And reigns the winter's pregnant silence still; No sign of spring, save that the catkins fill, And willow stems grow daily red and bright. These are days when ancients held a rite Of expiation for the old year's ill, And prayer to purify the new year's will.
