"The Benefits of Making Offerings. Important benefit of making light offerings is achieving Dharma wisdom. If we want to develop Dharma wisdom, then offer light. Many people might think if you are offering light, it should be just a butter lamp, a candle or an oil lamp. Thinking that you can’t offer the other lights in the house, for example, electric lights, is a very limited idea. Thinking that you can only offer candles is wrong. Whatever light is more clear and dispels darkness, that is the better light, so you can offer all the lights in the house. When you do a sadhana or an offering practice, you can offer those lights. By making light offerings, you are able to dispel the darkness of ignorance and achieve wisdom. By offering light, you are never in darkness while you are circling in Samsara. There will always be light. And offering light just one time to Buddha creates the Karma to have great wealth for many hundreds or thousands of lifetime.
