Light your heart, illuminate the world! Light is the vital energy needed by every living being. The dedication of light is a way to help all beings from all walks of life to obtain immeasurable light. After we pass on, the road to the netherworld is dark. To illuminate the road to the netherworld, it depends on how much light offering we provide in this lifetime. The more they are and the brighter the path. According to the law of mass-energy equivalence, energy can be converted into matter, and the energy can be stored for future use.
