Arjuna said I cannot see, O destroyer of Madhu, how can this Yoga by, Equanimity, which you have declared to me, be made to have a continual existence. For, O Krishna, mind is fickle, boisterous, perverse and obstinate; and I think to restrain it is as difficult as to restrain the wind.
अर्जुन उवाच योऽयं योगस्त्वया प्रोक्तः साम्येन मधुसूदन। एतस्याहं न पश्यामि चञ्चलत्वात् स्थिति स्थिराम्॥ चञ्चलं हि मनः कृष्ण प्रमाथि बलवद् दृढम्। तस्याहं निग्रहं मन्ये वायोरिव सुदुष्करम्॥
