युञ्जन्नेवं सदाऽऽत्मानं योगी नियतमानसः।
शान्तिं निर्वाणपरमां मत्संस्थामधिगच्छति।।6.15।।
6.15. Yoking his self (mind) incessantly in this manner, My devotee, with mind not attached to anything else, realises peace which culminates in the nirvana and is in the form of ending in Me.
6.10-15 Yogi etc. upto adhigacchati. Self : the mind. Let him yoke it : let him make it single-pointed. Always : not for a limited period of time. If the conditions like remaining alone etc., are fulfilled, this [controlling of mind] is possible and not otherwise. On account of the firmness of seat, the time-nerve (or the body ?) remains firm and due to this, mind remains firm. He, by whom the mental activities i.e., those that are in the form of intention, and other activities of the sense-organs are subdued i.e., are brought under full control; [he is the person of the subdued mental and sensual activities]. Holding : i.e., with effort. If the nose-tip is looked at, [it is possible] not to look at [different] directions. Let him remain endowed with the state of having Me alone as supreme goal. This is the meaning [here]. He who yokes i.e., concentrates his self (mind) in this manner, there arises for him Peace in which the culmination - as far as the end-is the same as attaining Me.
