The Yogins striving (for perfection) behold Him dwelling in the Self; but, the unrefined and unintelligent, even though striving, see Him not.

Yogis who strive see it established within themselves, but those who are unprepared within and lack awareness do not see it, even when they strive.

Krishna adds a sober note: effort alone is not enough. Yogis who strive with a prepared mind see the self established within. Others may also strive, but if they are akṛtātman, inwardly unformed or impure, and lack awareness, they still do not see it. The verse does not dismiss effort; it says effort must be joined to inner purification and attention. It warns Arjuna that spiritual practice is not a mechanical technique but a transformation of the person who practises it.
