Knowledge, Information And Experienced

1. How birth of Diya took place. 

Think of the man in the beginning, when there was nothing, and he felt himself absolutely weak. Just think of before even fire was invented. What was the situation of man? The weakest animal on the earth. 

Fire is perhaps the greatest discovery of man, not nuclear weapons, because it was fire that gave man tremendous courage. Then in the night he could make a bonfire and sleep around it; and the animals were afraid of fire so they would not come. Otherwise sleep was impossible – if you slept you were finished; any animal could take you away.

So when we light the diya it is out of our gratitude towards the fire. All other is our interpretation. 

2. The greatest lamp is the Sun, slowly but surely consuming itself so all the creatures on the Earth can live. The Sun only gives and asks for nothing. That is
why it is called a Devata – the one who gives.
