What man calls meaning, the thought, is the expression of the ultimate state of the cosmos. It is the dormant peace.
The dormant peace is our goal. But killing ourselves is not the dormant peace, because in our lives we can contribute much more to it.
Killing others is not either. Every person to whom we impart peace imparts it further. On and on this goes and a fan of peace unfolds through space and time.
That is our purpose. To strive for peace and to help creation to do the same.
