Gitaacharya to Arjuna:
Mans enemy is desire born of the Element of energy in the scheme of nature.
Insatiably ravenous and most wicked, it is the cause of all sin. This enemy of man attacks
judgment and puts it out of action.
As fire is
surrounded by smoke, as a mirror is covered over by dust, as the embryo is enclosed in the
womb, so is judgment, with which man is endowed, enveloped by desire. It seizes the senses
and the Will and finally judgment. It deceives, taking many forms, and disables the
soul from attaining jnaana.
Check the senses, therefore, at the very outset, O prince,
and vanquish this evil thing that is the enemy of all knowledge and enlightenment. The
rebellious senses are governed ultimately by Will, and though Will can be guided by
discrimination; this great enemy overcomes discrimination by its evil strength, and puts
it out of action. Realizing this danger, do thou exercise the inherent strength of thy
soul and defeat this elusive and terrible enemy and save thyself. -Gita III, 36-43
