"On my voyage back into the Ghetto, I wanted to take with me all the questions that had tormented me after the liberation. Why had the world learned nothing from our suffering? Were the Nazis only the most extreme example of the urge to do evil, or was the drive to destroy inherent in human nature? The Nazis were, for me, the most obvious channel through which the poison of hatred could flow freely—but the poison itself, where did it come from? What was its source? In writing about the Ghetto, I wanted to find that source. I wanted to discover the essence of our humanity, to touch upon the source, upon the core of the human soul and see it reflected in the soul of the Ghetto Jew, who had stood stripped of every shred of artifice and pretense necessary to leading a normal life. There, in the Ghetto, humans had faced humans without any embellishments or illusions. They had faced the brutality of their fellow human beings, as well as the knowledge of what that brutality meant to their own destinies. It was as if the dams of a river had opened within me and I became pregnant with the idea for my book. And so it was, that by the time I arrived in Montreal, I was doubly pregnant: pregnant with my daughter, who was born in Canada, and pregnant with my novel, which was born here as well, but many years later, when my daughter was already grown and my son was an adolescent. I called this novel about the death of the Jewish community of Lodz The Tree of Life."
