Light

Every major world religion speaks a language of light.

In the Brahmarahasya Upanisha it is pronounced;

• Brahma is the Light of lights.
• He is self-luminous.
• He is Supreme Light. 
• He is the ultimate light. 
• He is just an embodiment of light. 
• By His light all else shines.

Light in Hinduism is revered as a God. Diwali is the festival of lights when a billion Hindus. Sikhs and Jains light lanterns and small earthen lamps; lights awaken awareness of God and the triumph of good over evil

.

Genesis 1:3. And God said, Let there be light: and there was light.

"God is light and in Him there is no darkness." (1 John 1:5)

Muslims speak of Allah as the source of light — inspiring, motivating and leading God's people. (Sarah A-Nur 24:35 one of the most beautiful passages in the Qur'an)

The ancients understood that light was the purest form of energy.  Light not only reveals and measures, but light energizes too, hence a lamp, candle or any form of light is cherished in ceremonies and celebrations within all religions of this modern world.

Light is knowledge 

The brightness of the Deya is further philosophized as knowledge and darkness as ignorance. Knowledge eradicates ignorance. To worship knowledge one stimulates the intellect in the activated consciousness to recognize the creator and its creation. A lamp serves no purpose with the rising sun yet the Hindus light a lamp for all religious ceremonies and rituals. The burning of the lamp is submitted to the true spirit of existence, sustenance, sacrifice, knowledge and cosmic reality. Hence we light the lamp to submit down to knowledge as the greatest of all forms of wealth. Knowledge backs all our actions whether good or bad. We therefore have a lamp lit during all auspicious occasions as a witness to our thoughts and actions. In death, it follows us to the cremation grounds and witnesses the final farewell.
