चञ्चलं हि मनः कृष्ण प्रमाथि बलवद्दृढम्।
तस्याहं निग्रहं मन्ये वायोरिव सुदुष्करम्।।6.34।।
6.34 The mind verily is restless, turbulent, strong and unyielding, O Krishna: I deem it as difficult to control it as to control the wind.
6.34 Hi, for, O Krsna-the word krsna is derived from the root krs [Another derivative meaning may be-the capacity to draw towards Himself all glorious things of this and the other world.], in the sense of uprooting; He is Krsna because He uproots the defects such as sin etc. of devotees-; manah, the mind; is cancalam, unsteady. Not only is it very unsteady, it is also pramathi, turbulent. It torments, agitates, the body and the organs. It brings them under extraneous control. Besides, it is balavat, strong, not amenable ot anybodys restraint. Again, it is drdham, obstinate, hard as the (large shark called) Tantu-naga (also known as Varjuna-pasa). Aham, I; manye, consider; tasya, its-of the mind which is of this kind; nigrahah, control, restraint; to be (suduskaram, greatly difficult;) vayoh iva, as of the wind. Control of the wind is difficult. I consider the control of the mind to be even more difficult than that. This is the idea. This is just as you say.
