karma-bandhaś ca yan-mūlaḥ
svīkuryāt ko nu tad budhaḥ
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 Kṛṣṇa consciousness (sa vai manaḥ kṛṣṇa-padāravindayoḥ). Since the followers of the mind bring about material bondage, we should be very careful not to trust the mind.
