In the end, The treasure of life is missed by those who hold on and gained by those who let go
Laozi. . . the mind is desperate to fix the river {of events} in place: Possessed by ideas of the past, preoccupied with images of the future, it overlooks the plain truth of the moment.
LaoziEmpty 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 to the source is 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.
LaoziThose who know others are intelligent Those who know themselves have insight. Those who master others have force Those who master themselves have strength.Those who know what is enough are wealthy. Those who persevere have direction. Those who maintain their position endure. And those who die and yet do not perish, live on.
Laozi
