By bestowing sympathy on others we increase our own. Sympathy given can never be wasted. Even the meanest creature will respond to its heavenly touch, for it is the universal language which all creatures understand. I have recently heard a true story of a Dartmoor convict whose terms of incarceration in various convict stations extended to over forty years. As a criminal he was considered one of the most callous and hopelessly abandoned, and the warders found him almost intractable. But one day he caught a mouse - a weak, terrified, hunted thing like himself - and its helpless frailty, and the similarity of its condition with his own, appealed to him, and started into flame the divine spark of sympathy which smoldered in his crime-hardened heart, and which no human touch had ever wakened into life.
He kept the mouse in an old boot in his cell, fed, tended, and loved it, and in his love for the weak and helpless he forgot and lost his hatred for the strong. His heart and his hand were no longer against his fellows. He became tractable and obedient to the uttermost. The warders could not understand his change; it seemed to them little short of miraculous that this most hardened of all criminals should suddenly be transformed into the likeness of a gentle, obedient child. Even the expression of his features altered remarkably: a pleasing smile began to play around the mouth which had formerly been moved to nothing better than a cruel grin, and the implacable hardness of his eyes disappeared and gave place to a soft, deep, mellow light. The criminal was a criminal no longer; he was saved, converted; clothed, and in his right mind; restored to humaneness and to humanity, and set firmly on the pathway to divinity by pitying and caring for a defenceless creature. All this was made known to the warders shortly afterwards, when, on his discharge, he took the mouse away with him.
