In plain words
Striving yogins behold it dwelling within, in their own buddhi; but those whose inner being is unrefined, though they strive, do not perceive it, lacking discernment.
Word for word
And striving yogins see this [Self] abiding in themselves; even striving, those of unrefined self, lacking discernment, do not see it.

केचित्तु —
यतन्तः प्रयत्नं कुर्वन्तः योगिनश्च समाहितचित्ताः एनं प्रकृतम् आत्मानं पश्यन्ति ‘अयम् अहम् अस्मि’ इति उपलभन्ते आत्मनि स्वस्यां बुद्धौ अवस्थितम् । यतन्तोऽपि शास्त्रादिप्रमाणैः, अकृतात्मानः असंस्कृतात्मानः तपसा इन्द्रियजयेन च, दुश्चरितात् अनुपरताः, अशान्तदर्पाः, प्रयत्नं कुर्वन्तोऽपि न एवं पश्यन्ति अचेतसः अविवेकिनः ॥ ११ ॥
In plain words
Some, however, say this —
Those who strive, who make real effort, the yogis, their minds gathered into one point, see him, this very one we have been speaking of, as the Self. 'This I am,' they realize directly, finding him established right there, in their own understanding. But others strive too, using scripture and the like, and still fail: their inner being remains unshaped, unrefined; they haven't disciplined the senses or practiced austerity; they haven't let go of bad habits; their pride still runs unchecked. Even with all their effort, they do not see him this way, minds unexamined, still lacking real discernment.
Close to the Sanskrit
But some —
Those who strive, making effort, the yogis, with minds concentrated, see him — the one under discussion — as the Self: 'This I am' — thus they apprehend him, abiding in the Self, in their own intellect. Even though striving by scripture etc. as means, those of unperfected self, of unrefined self, [not perfected] by austerity and by conquest of the senses, unceased from bad conduct, of unquieted arrogance — even though making effort, they do not see thus — the unthinking, the undiscerning. || 11 ||
