Letting go is never easy. The desire to have, to hold, to possess and to control is part of our nature. But the more powerful part yearns to learn the lesson of growth and openness; to enter the mystery of secret loving without desiring, to live in emptiness and stillness and therefore in a state of receptivity and readiness so that the quality of our being and "our being present to" are all that matter.
What do we do with suffering? As far as I can see, we have two choices — we either transform our suffering into something else, or we hold on to it, and eventually pass it on.
In order to transform our pain, we must acknowledge that all people suffer. By understanding that suffering is the universal unifying force, we can see people more compassionately, and this goes some way toward helping us forgive the world and ourselves. By acting compassionately, we reduce the world's net suffering and defiantly rehabilitate the world. It is an alchemical act that transforms pain into beauty. This is good. This is beautiful.
To not transform our suffering and instead transmit our pain to others,...compounds the world's suffering. Most sin is simply one person's suffering passed on to another. This is not good. This is not beautiful.
The utility of suffering, then, is the opportunity it affords us to become better human beings. It is the engine of our redemption.
