In this verse, Krishna addresses the profound error of ego-identification that binds the soul to the cycle of action and reaction. By 'in spite of this' (evam sati), Krishna refers to the previous context where he explained the five factors of action, which prove that the individual self is not the sole architect of any outcome. To perceive the Self (Atman) as the isolated, independent 'doer' is a symptom of an 'impure intellect' (akrita-buddhi), one that has not been refined by the fire of discrimination or surrendered to the Divine will. It is a fundamental metaphysical blindness that mistakes the instrument for the Agent. This 'foolishness' (durmati) is not merely a lack of intellectual capacity, but a spiritual misalignment. When we identify the transcendental Atman—which is by nature actionless and pure—with the limited ego-construct that performs actions, we suffer the illusion of doership. Krishna is revealing that true wisdom lies in realizing the interplay of Gunas (modes of nature) while remaining anchored in the Witness-consciousness. Without this realization, one remains trapped in the 'I-maker' (ahankara), taking credit for successes and suffering the burdens of failure, thereby remaining disconnected from the truth of their own divine, non-dual nature.

True wisdom is the realization that the Atman is the eternal Witness, whereas the ego is merely a transient instrument within the cosmic orchestration of Prakriti.
