O Arjuna, wisdom is enveloped by this constant enemy of the wise in the form of desire, which is unappeasable as fire.

Knowledge is covered, son of Kunti, by this constant enemy of the wise, which takes the form of desire, an insatiable fire.

Krishna continues his description of desire (kāma). It covers knowledge (jñāna) and is the constant enemy even of the wise. It is likened to a fire that can never be filled: the more fuel it is given, the higher it burns. The image explains why satisfying desires does not end them. Each fulfilment feeds further craving. The verse warns that no one, however learned, is beyond the reach of this force, and so vigilance is needed by all who would keep their understanding clear.
