No person feels happy with living in Darkness. And Jyoti leads us from darkness to light! The lightening in the clouds, God, Sun, Moon and also twinkling stars emitting dim light to remove the darkness. The electric bulb cannot light up another bulb so the bulb is not worshipped but a Deepak takes pride in lightening up another Deepak at the cost of burning out itself so Deepak is worshipped.
Deepak doesn't spread fire it spreads light because fire burns up everything, whereas a lamp and a candle destroy darkness and spreads light.
A Flame can infuse knowledge, and wisdom and thus make others happy. The navigators remain on the right track by Seeing the beams of a light house.
Flame is considered to be the source of infinite energy of positive current. It is believed to be a germ killer. That's why in Hindu mythology Flame is considered to be a Worshipping thing.
