Here is the Sanskrit anuvad, Hindi anuvad, and English translation of Purushottama Yoga Chapter 15, Verse 15.11.
Sanskrit
यतन्तो योगिनश्चैनं पश्यन्त्यात्मन्यवस्थितम् । यतन्तोऽप्यकृतात्मानो नैनं पश्यन्त्यचेतसः ॥ १५.११ ॥
Hindi
यत्न करने वाले योगी जन भी अपने ह्रदय में स्थित इस आत्मा को तत्व से जानते हैं ; किंतु जिन्होंने अपने अन्त:करण को शुद्ध नहीं किया है, ऐसे अज्ञानी जन तो यत्न करते रहने पर भी इस आत्मा को नहीं जानते ।
English
Those people who are pure at heart and are constantly striving to see Me, inevitably see Me, the Lord who dwells in their own heart. However those people who are impure at heart and in their minds never perceive Me, the Supreme Spirit, no matter how much they strive.
