all we can be sure of

     The only danger is not going far enough…we are speaking here of the human spirit. If we go deep enough, we reach the common life, the shared experience of man, the world of possibility.
     If we do not go deep, if we live and write half-way, there are obscurity, vulgarity, the slang of fashion, and several kinds of death.
     All we can be sure of is that our art has life in time, it serves human meaning, it blazes on the night of the spirit; all we can be sure of is that at our most subjective we are universal; all we can be sure of is the profound flow of our living tides of meaning, the river meeting the sea in eternal relationship, in a dance of power, in a dance of love.
