In this verse, Lord Krishna defines the hallmark of a 'Sthitaprajna,' or one whose wisdom is firmly established in the Self. The spiritual struggle of the human condition arises from the constant binary of attraction and repulsion—our tendency to cling to that which we deem auspicious and recoil from that which we deem unfavorable. Krishna argues that true transcendence is not the absence of external events, but the complete neutrality of the internal witness. By shedding 'abhisneha'—the binding, possessive affection that tethers the soul to the fruits of karma—the seeker stops identifying as a victim of circumstance and begins to see all experiences as mere waves on the ocean of existence. This state represents the transition from a life governed by impulsive ego-reactions to a life anchored in the immutable Brahman. When one ceases to 'rejoice' in prosperity or 'despise' adversity, the mind is purified of the turbulent fluctuations that usually obscure divine knowledge. This detachment is not a state of cold, robotic indifference, but rather a state of profound peace where the seeker recognizes that the Divine presence permeates both the 'good' and the 'bad.' It is here, in this state of equanimity, that the intellect stops chasing the shadows of the world and realizes its inherent oneness with the Eternal.

True wisdom is the state of abiding in the immutable Self, where the mind remains unmoved by the inevitable dualities of life because it has recognized the Divine as the only reality.
