The things that have acquired unity are these: Heaven by unity has become clear; Earth by unity has become steady; The Spirit by unity has become spiritual; The Valley by unity has become full; All things by unity have come into existence.
When you stand with your two feet on the ground, you will always keep your balance.

Without looking through the window, you can see Heaven's Way.
He who controls the past controls the future.
Attain utmost emptiness. Abide in steadfast stillness.
