तत्त्ववित्तु महाबाहो गुणकर्मविभागयोः। गुणा गुणेषु वर्तन्त इति मत्वा न सज्जते ॥

tattva-vit tu mahā-bāho guṇa-karma-vibhāgayoḥ guṇā guṇeṣhu vartanta iti matvā na sajjate

But he, O mighty-armed, who knoweth the essence of the divisions of the qualities and functions, holding that "the qualities move amid the qualities," is not attached.

In plain words: Krishna says the person who truly understands how nature's qualities work sees that they are only acting on each other. So this person does not get attached.
