From Krishna's side, naked or dressed, He is Krishna. And from our side, if we nicely dress Krishna and nicely feed Him, He is appreciating our service and we are certainly benefited. Krishna is the same; He does not require us to dress Him, or feed him, etc., but the more I serve by dressing, feeding and caring for Him, He appreciates the service, and I become more Krishna Conscious.
Letter to Satsvarupa, 14 November, 1968
