Letters of Sri Aurobindo
Volume IV - Part 2
You do not seem to have a correct idea of the nature of vital 
desire. Vital desire grows by being indulged, it does not become satisfied. If your desire were indulged, it would begin to grow more and more and ask for more and more. That has been our constant experience with the sadhaks and it confirms what has always been known about desire. Desire and envy have to be thrown out of the consciousness – there is no other way to deal with them.
