Desire is not wrong. Having so much of desires, you have never time to fulfil even one desire is wrong. Desire to have a cup of coffee is not wrong. But by the time coffee is ready, you are already worried about having a buttermilk.
By the time buttermilk is ready. you have already started worrying about the nectar. But finally from the morning till night you never drank anything. That is what is wrong.
