Bhagavad Gita 15.11

यतन्तो योगिनश्चैनं पश्यन्त्यात्मन्यवस्थितम्।यतन्तोऽप्यकृतात्मानो नैनं पश्यन्त्यचेतसः ॥१५.११॥

yatanto yoginaścainaṃ paśyantyātmanyavasthitamyatanto’pyakṛtātmāno nainaṃ paśyantyacetasaḥ

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