Darkness is similar to endless meditation, which is sealed, secret and gloomy.
We continuously overturn or revise our directions, but the future is still full of uncertainty, like a shadow which cannot be grasped.
Light represents vision while shadow represents illusion, accompanied by which we walk as well as think. It is indispensable to stop at the right moment to excavate new things. Honesty and flattery, bona fides and absurd, keep the balance between black and white.
Things that are distinct in the light become invisible in the dark. Shadow badgers with the light in darkness. They connect with each other but are still individual.
Boundaries interweaved like a network of nerves, in which light and shadow fight with each other.
