चञ्चलं हि मनः कृष्ण प्रमाथि बलवद्दृढम्।
तस्याहं निग्रहं मन्ये वायोरिव सुदुष्करम्।।6.34।।
6.34. O Krsna ! The mind is indeed unsteady, destructive, strong and obstinate; to control it, I believe, is very difficult, just as to control the wind.
6.33-34 Yo Yam etc. Cancalam etc. By this and which, the two words denoting [respectively] what is actually perceived and what is not perceived, the following is indicated : Thanks to the series of methods spoken just before by the Bhagavat, the Brahman is of course clear and has been no doubt shown as if by perception. Yet, It remains at agreat distance due to the unsteadiness and wickedness of the mind, and It behaves as if It is beyond perception. [Destructive] : The mind destroys both the visible and invisible [ends of mans action]. Strong : Powerful. Obstinate : impossible to ward off from evil acts. Now the answer -
Chanchalam hi manah krishna pramaathi balavad dridham; Tasyaaham nigraham manye vaayoriva sudushkaram.
