यदा हि नेन्द्रियार्थेषु न कर्मस्वनुषज्जते ।
सर्वसङ्कल्पसन्न्यासी योगारूढस्तदोच्यते ।। ६.४ ।।

yadā hi nendriyārtheṣu na karmasv-anuṣajjate |
sarva-saṅkalpa-sannyāsī yogārūḍhas-tadocyate ||6.4।।

How does a seeker, who has remained active and has been pursuing the yoga, know that he has reached the required level of yogic attainment? Krishna takes up the subject matter next:

When, by virtue of renunciation of all desire-oriented thoughts, the seeker does not feel any attachment with either the sensory objects or his actions, then is he regarded as a yoga-arudhah (having ascended to the pedestal of yoga).

Krishna makes it clear that by the pursuit of yoga, the way he has described and explained it, the mind of the seeker gets purified and sublimated by every action. This becomes evident by the note of renunciation that emerges in the seeker’s mind towards desires and desire motivated pursuits. This is the renunciation that verily counts in spiritual seeking and attainment. The identified mind becomes disidentified. The agitated mind becomes free of such agitation. What causes agitation and agony is not the mind but the desire-oriented thoughts it generates and sustains. When the same mind learns to function, free of desire-oriented constrictions and imaginations, it becomes light, peaceful and expansive. The benefit of renunciation is precisely this. Krishna calls it sankalpa sannyasa or sankalpa tyaga. For him sannyasa denotes tyaga.

What can a seeker forego or give up by way of tyaga? None can abandon his body, for it lives governed by the laws of Nature. None can leave his mind also. Thus, if anything can be renounced, it is the wrong evaluations, assessments of the mind, and the erroneous identification and attachment these bring about. The mind is free to do this. Karmayoga is a pursuit in and by which, this purification and purging is constantly attempted and achieved, a requisite for fruitful meditation.
