Some geese and cranes were feeding together in the same field one day, when a bird-catcher suddenly came upon them. Since the cranes were slim and light they could fly off right away and escape the bird catcher’s nets. The geese, however, weather down by their fat, could not take off so easily and were all captured.
Old Learning: Those who are caught are not always the most guilty.
Tread where you can manage. Knowing own strength and weakness is critical.
