Conversation between an Indian mythologist Devdutt Pattanaik and Alexander the Great:

The world conqueror apparently met what he called a ‘gymnosophist’ – a naked, wise man, possibly a yogi – sitting on a rock and staring at the sky, and asked him, “What are you doing?”

“I’m experiencing nothingness. What are you doing?” the gymnosophist replied.

“I am conquering the world,” Alexander said.

They both laughed; each one thought the other was a fool, and was wasting their life.
