The summary of anecdote of the moth and the lamp?

Two moths are flying around a flame. The elder moth warns the younger one to stay away from the flame, but the younger one disobeys, his wings catch fire, and he dies. Jose Rizal's mother told him the story to get him to pay attention to his schoolwork while he was watched the moths encircle the flame to their table lamp. He immediately understood what might happen to him if he exercised his right to freedom in life.
