Should a greater ecological awareness begin to shape our thinking, new symbols would arise that could bind the scientific and the spiritual and would reinfuse all life with the essence of the sacred. We would be increasingly capable of envisioning the "blue, true dream" that is the living Earth luminous in the darkness of the surrounding sky.
The Way is infinitely high, unfathomably deep. Enclosing heaven and earth, receiving from the formless, it produces a stream running deep and wide without overflowing. Opaque, it uses gradual clarification by stillness. When it is applied, it is infinite and has no day or night. It is restrained but can expand, it is dark but can illumine; it is flexible but can be firm. It absorbs the negative and emits the positive, thus displaying the lights of the sun, moon and stars.
