The fulfillment we seek in this world lies in the spiritual work of overpowering the consciousness that life is "only about me."
If we spend our days chasing things that do not satisfy our soul’s deepest desires for fulfillment, we will eventually feel empty and joyless. If we work only to serve the body, we will starve this all-important aspect of our being.
Ultimately, we discover that deep, lasting happiness can come only when our souls are fed—and the food that satisfies the soul comes to us when we manage to become proactive beings of sharing.
This does not mean we need to renounce the physical world, but rather to transcend its control over us.
