This verse encapsulates the culmination of the spiritual path, where the dualistic boundaries of the self dissolve into the infinite expanse of the Divine. Lord Krishna defines the 'Rishi' not merely as a hermit, but as one who has achieved a radical internal transformation. The purging of 'kalmaṣha' (sins or mental impurities) is the clearing of the mirror of the heart, allowing the reflection of the Self to appear untarnished. When 'dvaidhā' or duality—the oscillation between likes and dislikes, existence and non-existence—is annihilated, the seeker ceases to see the world as a source of conflict and begins to perceive it as an expression of the one Brahman. Crucially, Krishna anchors this state of absolute liberation in the concept of 'sarva-bhūta-hite ratāḥ'—finding joy in the welfare of all beings. This is the hallmark of the mature mystic: the realization that the self is not isolated. Because the sage experiences the same Brahman in themselves as they do in others, service becomes a natural, effortless act of worship. Liberation (Brahma-nirvāṇa) is therefore not an exit from the world, but a profound shift in perception that transforms every action into a sacred offering, unifying the stillness of meditation with the movement of compassionate service.

True liberation is the radical synthesis of a quieted mind and an active heart, where the realization of non-duality naturally blossoms into selfless love for all existence.
