Any person pursuing self-knowledge or meditation generally try to keep aside all desires. They don't see that even to attain the goals of meditation they are driven by some desire. So desire has a positive role too. Basically dsire is like fuel, it drives us, it is only the direction which can be examined. What one needs to desire is right knowledge, moksha, company of enlightened soul etc. So never be in a hurry to keep aside desire, but desire great things intensely.
