| कर भला, तो हो भला |
As you sow, so do you reap.

It is human tendency to expect good things in return. Without incentive, we wont indulge in good deeds, is it? We need some "promising" verses (like the hindi ones above) or some "threatening dire consequences" proverb (like the english one above) to motivate us to do the right thing.

Well, its not as bad as it sounds. Whatever works, as they say. Anyway, now the times seem to be such that even if the above incentives work, thats a big achievement in itself.
