Indian American Saying (about Character, Decisions, Morality)

'It is as though I have a black dog and a white dog inside me fighting each other constantly.' The black dog, he explained, represented evil and the white dog represented good. The missionary asked him, 'Which dog wins the fight within you?' After several moments of silence, the native said, 'The dog that wins is the one I feed and the dog that loses is the one I starve.'
