In plain words
The deluded do not perceive it when it departs, remains, or experiences while joined to the guṇas; those with the eye of jñāna see.
Word for word
Departing, or staying, or even enjoying, joined with the guṇas, the deluded do not perceive [it]; those with the eye of knowledge see.

एवं देहगतं देहात् —
उत्क्रामन्तं देहं पूर्वोपात्तं परित्यजन्तं स्थितं वापि देहे तिष्ठन्तं भुञ्जानं वा शब्दादींश्च उपलभमानं गुणान्वितं सुखदुःखमोहाद्यैः गुणैः अन्वितम् अनुगतं संयुक्तमित्यर्थः । एवंभूतमपि एनम् अत्यन्तदर्शनगोचरप्राप्तं विमूढाः दृष्टादृष्टविषयभोगबलाकृष्टचेतस्तया अनेकधा मूढाः न अनुपश्यन्ति — अहो कष्टं वर्तते इति अनुक्रोशति च भगवान् — ये तु पुनः प्रमाणजनितज्ञानचक्षुषः ते एनं पश्यन्ति ज्ञानचक्षुषः विविक्तदृष्टयः इत्यर्थः ॥ १० ॥
In plain words
So this is the self at home in the body. Now, as it leaves that body —
Departing, leaving behind the body he had taken up before; or simply remaining, staying put in the body; or enjoying, tasting sound and the rest — whichever of these three he is doing, he is always joined with the guṇas, carried along by pleasure, pain, and delusion, bound up with them, swept along by them. And even though he stands in plain view, right within reach of ordinary sight, the deeply deluded still cannot see him, their minds dragged in every direction by the sheer pull of enjoying what is seen and unseen. 'What a pity,' the Lord says, grieving for them. But those who have the eye of knowledge, opened by real means of knowing, they do see him: eyes of knowledge, a vision that discerns what is real.
Close to the Sanskrit
Thus, situated in the body — from the body —
Departing — the body previously acquired, abandoning; or else remaining, staying in the body; or enjoying, and perceiving sound etc. — 'accompanied by the guṇas' means accompanied, by the qualities of pleasure, pain, delusion etc., followed, gone-along-with, joined: that is the meaning. Even though thus characterized, though he has come within the very range of direct perception, the utterly deluded do not perceive him, being in many ways deluded, their minds dragged by the force of the enjoyment of seen and unseen objects — 'Alas, what a pity!' — thus the Lord commiserates. But those, again, who have the eye of knowledge produced by valid means of knowledge, they see him — having the eye of knowledge, of discerning vision: that is the meaning. || 10 ||
