आवृतं ज्ञानमेतेन ज्ञानिनो नित्यवैरिणा। कामरूपेण कौन्तेय दुष्पूरेणानलेन च॥
avritam jnanam etena jnanino nitya-vairina kama-rupena kaunteya dushpurenanalena cha
Translation
O son of Kunti, wisdom is covered by this eternal enemy of the wise in the form of desire, which is like an insatiable fire.
Commentary
Desire is called an insatiable fire because fulfilling one desire only creates more desires. Like fire that grows bigger with fuel, desire grows with gratification rather than diminishing.
