A lamp kept on mound illumines the area; if kept in a pit, it is as if it were not. A virtue that is practised is a lamp that shines for all; good thoughts and good deeds have a way of influencing others. The gems of wisdom, the light of intuitive experience should not be kept away from fellow – men. They have to be shared, even at the cost od one’s life. That was the lesson Jesus taught and symbolised.
