I can’t even attempt to pretend that I know what the play “Etty” is about, nor can I grasp the full dimension of the spirituality of either Susan Stein’s performance or Etty Hillesum’s writing. All I can say is that this play, which I saw at the Parker B. Poe Theater at Lincoln Academy, is one-of-a-kind, with a distinct level of dedication that the author as well as the actor, Stein, has paid to this production, and a depth of spiritual discussion this play has brought to various groups, from middle schools to high schools, from prisons to large city theaters.
