SB 5.6.5

TRANSLATION
The mind is the root cause of lust, anger, pride, greed, lamentation, illusion and fear. Combined, these constitute bondage to fruitive activity. What learned man would put faith in the mind?

PURPORT
The mind is the original cause of material bondage. It is followed by many enemies, such as anger, pride, greed, lamentation, illusion and fear. The best way to control the mind is to engage it always in Krsna consciousness (sa vai manah krsna-padaravindayoh [SB 9.4.18]). Since the followers of the mind bring about material bondage, we should be very careful not to trust the mind.
