One fine day, the supreme Indian Lord, Vishnu, met up with Indra, the Indian god of the sky, both in disguise.
On that day, when they were discussing some important things, Indra bragged to the great Lord Vishnu about how he could stir up violent storms without harming the people.
Ha! Lord Vishnu, I am the most unique of all the gods because I can make my tornadoes not harm people. None of the gods compare with me, not even you can do so!
Vishnu took Indra's comments lightly, but he couldn't keep calm one day when Indra mentioned about him being the new supreme lord, which included dethroning Vishnu. Indra however, kept a calm and arrogant face as usual.
He spoke loudly with anger, "INDRA, HOW DARE YOU SPEAK ABOUT DETHRONING ME!
Vishnu cooled down and asked Indra to demonstrate his talent.
Okay Indra, let's see what you can do.
Ha! Watch me!
And so, Indra spun as fast as the wind and turned into a big, graceful, harmless, colorful tornado. He spun by houses, harming no one and snickered at Vishnu. As being the lord almighty, Vishnu knew what was happening, and he was enraged.
Vishnu cursed Indra by saying that, "with your boastfulness and pride, you have lost consciousness of who you are talking to, from now on, tornadoes will be thought of monstrous disasters by people. Let that remind you of who you are." From then on, Indra lived in regret about his decisions, and his despair turned his tornadoes a miserable color as well.
