"I don't think I am ghoulish in saying that I would like them, and every morally responsible citizen of the world, particularly my fellow Australians of the World War II period, to refresh their memories by referring regularly to the photographic record of the Hiroshima-Nagasaki happening — the rags of human flesh, the suppurating sores, the despair of families blown apart, the disturbed minds, the bleak black gritty plains where the homes of human beings like you and I once stood. Most of all, I would like every Australian couple born since Hiroshima and Nagasaki were blasted out of existence to consult these photographic records and for ever after do all in their power to prevent the children they are creating from suffering a fate similar to that thrust upon the children of those two Japanese cities. Let us rouse ourselves and realise this is what we shall have to face."

“The essence of what you have to say you pick up before you're twenty.”

“The ideal of non-attachment has been preached again and again in the course of the last 3000 years. It is found in Hinduism, the teachings of Buddha, the doctrine of Lao Tsu, in the philosophy of the Greek Stoics. The Gospel of Jesus is essentially one of non-attachment to the things of this world, and of attachment to God. What the Jewish philosopher Spinoza calls "blessedness" is simply the state of non-attachment, just as Spinoza's "human bondage" is the condition of one who identifies himself with his own desires, emotions, and thought processes, or with their objects in the external world.”

“In the 14th Century an anonymous English mystic wrote a book called The Cloud of Unknowing, the main theme of which is that God cannot be apprehended by man's intellect and that only love can pierce the "cloud of unknowing" which lies between Him and us. I feel that in my own life anything I have done of possible worth has happened in spite of my gross, worldly self. I have been no more than the vessel used to convey ideas above my intellectual capacities. When people praise passages I have written, more often than not I can genuinely say, 'Did I write that?' I don't think this is due to my having a bad memory, because I have almost total recall of trivialities. I see it as evidence of the part the supernatural plays in lives which would otherwise remain earthbound.”

“Many of those who hear me believe I am putting on an act, while others who had considered I am one who surely knows the answers, are depressed to find that, by my own admission, I don't. What I do know for certain is that what is regarded as success in a rational materialistic society only impresses superficial minds. It amounts to nothing and will not help us rout the destructive forces threatening us today. What may be our salvation is the discovery of the identity hidden deep in any one of us, and which may be found in even the most desperate individual, if he cares to search the spiritual womb which contains the embryo of what can be one's personal contribution to truth and life.”

“Conversation is imperative if gaps are to be filled, and old age, it is the last gap but one.”

“In my books I have lifted bits from various religions in trying to come to a better understanding; I've made use of religious themes and symbols. Now, as the world becomes more pagan, one has to lead people in the same direction in a different way.”
