The Supreme Personality of Godhead said: My dear Uddhava, a person bereft of intelligence first falsely identifies himself with the material body and mind, and when such false knowledge arises within one’s consciousness, material passion, the cause of great suffering, pervades the mind, which by nature is situated in goodness. Then the mind, contaminated by passion, becomes absorbed in making and changing many plans for material advancement. Thus, by constantly thinking of the modes of material nature, a foolish person is afflicted with unbearable material desires.
