You could say that the happiness of a person can be described mathematically as:
Happiness_formula
So if you have ten desires and five are fulfilled, you have fifty percent happiness. If ten are fulfilled, you have one hundred percent happiness. The more desires you have, the harder it will be to fulfil them all, and so the less happy you will be. Happiness is inversely related to the number of desires. What happens when you have no desires at all? The denominator becomes zero. Anything you divide by zero is infinity. If you have zero desires, limitless will be your happiness.
In this desireless state, we don’t expect anything.When we don’t expect anything, we don’t play games with ourselves and others. We don’t manipulate others because we don’t expect anything from anyone.
