After a long time I watched Ramayana yesterday evening. Got a lot to learn from all the characters:

When Ravan was dying, Shri Ram sent Laxman to him to learn something. Laxman stand near his head and asked for teaching. Ravan rebuked him saying sit near my feet if you want to be disciple, not on my head. Laxman did so. Ravan was the greatest teacher of political science, I never knew.

Then Ravan Told him about Politics and Niti which mainly said

1- do not be enemy of your charioteer, your gatekeeper, your cook and your brother, they can harm you anytime

2- do not think you are always a winner, even if you are winning always

3- Always trust the minister, who criticises you

4- never think your enemy is small or powerless, like i thought for Hanuman

5- never think you can outsmart the stars, they will bring you what you are destined to

6- Either love or hate god but both should be immense and strong

Ravana taught him that a king who is eager to win glory must suppress greed as soon as it lifts its head, and welcome the smallest chance to do good to others, without the slightest procrastination. He (Ravana) had learnt the lesson through bitter experience. Greed arises from attachment to the senses and catering to them. Put them in their proper place; they are windows for knowledge, not channels of contamination.--
