No self-knowledge without Yoga.
A few, however,
यतन्तो योगिनश्चैनं पश्यन्त्यात्मन्यवस्थितम् ।
यतन्तोऽप्यकृतात्मानो नैनं पश्यन्त्यचेतसः ॥ ११ ॥
yatanto yoginaścainaṃ paśyantyātmanyavasthitam .
yatanto’pyakṛtātmāno nainaṃ paśyantyacetasaḥ .. 11 ..

Those who strive, well balanced in their mind, behold Him, the Self, dwelling in their own mind (buddhi): they recognise Him, “This I am.” But though striving to know Him by means of proper authorities such as the scriptures (sastra), men of unrefined self—whose self (mind) has not been regenerated by austerity (tapas) and subjugation of the senses, who have not abandoned their evil ways, whose pride has not been subdued,—behold Him not.‡
A mere study of scriptures, aided by reason and reflection, will not be of much avail to those whose minds are still impure and who therefore have not yet realised the distinction between the permanent and the impermanent, the real and the unreal.—A.
Immanence of the Lord, (1) as the all-illumining Light of Consciousness.
That Goal (the Supreme Self) which even such luminaries as fire and sun, the illuminators of all, do not illumine : which having reached, the seekers of moksha never return towards samsara; of which the Jivas (individual souls) are only parts manifesting themselves in conformity to the upadhis, as the akasa (space) in a jar is but a portion of the all-pervading akasa,—with a view to show that that Goal is the essence of all and the real basis (i.e., object) of all experience, the Lord proceeds in the next four verses to give a brief summary of His manifestations.
