Meaning of flight beyond a way of travel to get a breadcrumb

…Jonathan found himself thinking time and again of the Earth from which he had come. If he had known there just a tenth, just a hundredth, of what he knew here, how much more life would have meant! He stood on the sand and fell to wondering if there was a gull back there who might be struggling to break out of his limits, to see the meaning of flight beyond a way of travel to get a breadcrumb from a rowboat. Perhaps there might even have been one made Outcast for speaking his truth in the face of the Flock. And the more Jonathan practiced his kindness lessons, and the more he worked to know the nature of love, the more he wanted to go back to Earth. For in spite of his lonely past, Jonathan Seagull was born to be a instructor, and his own way of demonstrating love was to give something of truth that he had seen to a gull who asked only a chance to see truth for himself.
