I know there is infinity beyond ourselves. I wonder if there is infinity within.

I believe the risks I take are justified by the sheer love of the life I lead.

We are in the grip of a scientific materialism, caught in a vicious cycle where our security today seems to depend on regimentation and weapons which will ruin us tomorrow.

After my death, the molecules of my being will return to the earth and sky. They came from the stars. I am of the stars.

This is earth again, the earth where I've lived and now will live once more ... I've been to eternity and back. I know how the dead would feel to live again.
