In this profound verse, Lord Krishna shifts the focus from external ritualistic duties to the internal state of the enlightened sage. While the previous verses emphasize the necessity of Karma Yoga (selfless action) to maintain world order, this verse identifies the destination of such a life: the state of Sthitaprajna, or the one established in the Self. When a human being moves beyond the sensory stimulation of the world and finds the inexhaustible source of joy within, their dependence on external outcomes ceases. This is not an invitation to laziness, but a description of one who has transcended the need for action born of desire or compulsion. The 'duty' (karya) that ceases is not the movement of the body, but the inner restlessness and the egoic sense of 'doership' that drives human toil. For such an individual, action becomes a spontaneous overflow of divinity rather than a calculated endeavor to achieve personal gain or fulfill egoic obligation. This state of absolute inner satiety signifies the complete integration of the practitioner with the Divine. When the seeker realizes that the Self (Atman) is the reservoir of all contentment, the world no longer appears as a place of lack or a series of transactions to be managed. The person who is 'atmarati' (rejoicing in the Self) moves through the world like a river moving toward the ocean—effortless, graceful, and fully one with the source of existence.

True liberation is the realization that the Self is the only source of lasting satisfaction, rendering all ego-driven duty and external craving obsolete.
