The Way that can be experienced is not true; The world that can be constructed is not real. The Way manifests all that happens and may happen; The world represents all that exists and may exist. To experience without abstraction is to sense the world; To experience with abstraction is to know the world. These two experiences are indistinguishable; Their construction differs but their effect is the same. Beyond the gate of experience flows the Way, Which is ever greater and more subtle than the world.
Lao Tse - Tao Te Ching
