आवृतं ज्ञानमेतेन ज्ञानिनो नित्यवैरिणा।
कामरूपेण कौन्तेय दुष्पूरेणानलेन च।।3.39।।
।।3.39।।और हे कुन्तीनन्दन इस अग्निके समान कभी तृप्त न होनेवाले और विवेकियोंके नित्य वैरी इस कामके द्वारा मनुष्यका विवेक ढका हुआ है।
The intellect of one who even has understanding of atma tattva or soul realisation becomes clouded by the eternal enemy known as kama or lust and which generates fascination and excitement for enjoying the objects of the senses. The word duspurena means insatiable, it can never be satisfied. It constantly hungers for sense gratification even if it is inaccessible to get and impossible to have still kama yearns for it. It is anala or inexhaustible as nothing ever completely satisfies kama permanently. When the object of its desires has been acquired and the senses fully gratified then at once kama wants more and looks for something new. It is never satisfied. In what way kama utilises itself to envelope the atma or soul Lord Krishna reveals next.
