If you light a lamp for somebody, it will also brighten your own path. ~ Buddist Saying

Lamps are fire. Fire is the trigram Li standing on the South. In the sign of Li the creatures are allowed to perceive each other. To see things is bringing them into light. To see people is to understand them. Lamps show things in best light, bring forth, intelligence, nobility and warmth.
