Chanakya was the mentor, guide and prime minister of Emperor Chandragupta Maurya. His words were very wise when it came to explaining human nature and ways of actual world.
Here is a story about him, from storybooks, no not of its authenticity though!
A young warrior was returning from war he noticed a Brahmin digging a hole under the scorching sun. When he came
closer he noticed that he was digging a hole near a thorny bush. Curious he asked what the Brahmin was doing!
The Brahmin answered that a thorn of that bush pierced his flesh, so he is pulling it out with its roots, so that it loses its existence forever!
That warrior was Chandragupta Maurya and the Brahmin was Chanakya.
