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.
Communication with God is a deep inner knowing that God is within you and around you. God "speaks" through the still, small voice within. When you have constant communion with God, a constant receiving from within, there is never any doubt; you know your way. You become an instrument through which a job is done, therefore you have no feeling of self-achievement... The main things, if you are to find inner peace, are to bring your life into harmony with the laws which govern this universe (these are the same for all of us), and to find and fit into your special work in this world -- your job in the divine plan.
