There is the story of a young man who was riding a cycle on a dark night along a crowded road; the policeman on duty asked him to stop and alight, for, he had no lamp on his cycle. The fellow, however, shouted, "policeman, keep away, of course, I have no lamp; but, beware, I have no brake, either!"
That is the pathetic condition of everyone now. No one has the lamp of wisdom, or the brake of sense-control. How then can they go along the road to Ânanda, without causing injury to themselves or others? The cyclist must have both; man too has need of wisdom and self-control. Or else, he is certain to ruin this chance he has got, to save himself.
