Someone will say, 'Yes, once I was very friendly and loving.' And if you ask him, 'Why not today?' He will answer, 'I was digging and I found mud.' But in every place you dig there is water. One need only dig deep enough, until one has found water. If one does not dig till one finds water, one only gets mud. Those who are disappointed in human nature and those who allow their heart to become cold because of this have lost a great deal. Somebody once said to me, 'I have lost my friend, and since then I have lost sympathy for human nature.' And I said, 'Your first loss was not so great, but I pity you for your second loss. It was then that you should have kept your sympathy.'
