आवृतं ज्ञानमेतेन ज्ञानिनो नित्यवैरिणा।
कामरूपेण कौन्तेय दुष्पूरेणानलेन च।।3.39।।
3.39 O Arjuna, wisdom is enveloped by this constant enemy of the wise in the form of desire, which is unappeasable as fire.
3.39 Jnanam, Knowledge; is avrtam, covered; etena, by this; nityavairina, constant enemy; jnaninah, of the wise. For the wise person knows even earlier, I am being induced by this into evil. And he always [Both at the time when desire arises in him, and also when he is forced to act by it.] feels distressed. Therefore, it is the constant enemy of the wise but not of a fool. For the fool looks upon desire as a friend so long as hankering lasts. When sorrow comes as a conseence, he realizes, I have been driven into sorrow because of longings, but certainly not earlier. Therefore it is the constant enemy of the wise alone. In what form? Kama-rupena, in the form of desire-tha which has wish itself as its expression is kama-rupa; in that form-; (and) duspurena, which is an insatiable; analena, fire. That which is difficult to satisfy is duspurah; and (derivatively) that which never has enough (alam) is analam. Again, having what as its abode does desire, in the form of a viel over Knowledge, become the enemy of all? Since when the abode of an enemy is known, it is possible to easily slay the enemy, therefore the Lord says:
Aavritam jnaanam etena jnaanino nityavairinaa; Kaamaroopena kaunteya dushpoorenaanalena cha.
