Empty your mind of all thoughts. Let your heart be at peace. Watch the turmoil of beings, but contemplate their return. Each separate being in the universe returns to the common source. Returning is the source of serenity.If you don“t realize the source, you stumble in confusion and sorrow. When you realize where you come from, you naturally  become tolerant, disinterested, amused, kindhearted as a grandmother, dignified as a king. Immersed in the wonder of the Tao, you can deal with whatever life brings you, and when death comes, you are ready.
