There are three approaches to dealing with this world:
One is to remain aloof as the sun. The world will benefit from your light, but you will remain distant and removed. You will invest little in this world and so have little to lose.
Another approach is to wane and wax as the moon—to suffer the scars and bruises of life, delight in its offerings, thirst for its rewards, and tremble at its horrors—to invest everything and risk losing it all.
Or you could be both the sun and the moon at once. You could feel meaning and purpose in every episode of life, no matter how small. And, at the same time. remain above it all.
What is the secret? It is memory.
Even as you invest yourself in this world, remember you are not the body, but the soul.
