"One never left a meeting with him feeling indifferent... He spoke slowly and quietly, weighing each word. He never said anything foolish. There was something sad in him, and he often behaved strangely. Once he arrived unexpectedly and he told me that Buddhism was a good religion; that though he was a prince, Buddha had done much to improve the lot of the poor. Then, as suddenly as he had arrived, he left. He was always very affectionate with me. [Oriana Fallaci: You're unable to see him as an enemy, isn't that true, Holiness?] Yes. Speaking as a Buddhist, I cannot accept the word enemy. ... Mao Tse-tung is neither cunning nor diplomatic. I told him what his generals were doing in Tibet, and he understood. Perhaps he couldn't stop them. Or perhaps he has changed. I am unable to reconcile the Mao Tse-tung I knew with the Mao Tse-tung of today. He must be in the grip of some madness or some infirmity. The cultural revolution, for example. The name is lovely, but there is no substance: it's the dementia of an old man. I cannot see him in this dementia."
