चञ्चलं हि मनः कृष्ण प्रमाथि बलवद् दृढम् | तस्याहं निग्रहं मन्ये वायोरिव सुदुष्करम् ||६-३४||

cañcalaṃ hi manaḥ kṛṣṇa pramāthi balavad dṛḍham . tasyāhaṃ nigrahaṃ manye vāyoriva suduṣkaram ||6-34||

"6.34 For the mind is fickle, O Krsna, impetuous, powerful and stubborn. I think that restraint of it is as difficult as that of the wind."
