मनुष्याणां सहस्रेषु कश्चिद्यतति सिद्धये ।
यततामपि सिद्धानां कश्चिन्मां वेत्ति तत्त्वतः ॥७.३॥

manuṣyāṇāṃ sahasreṣu kaścidyatati siddhaye
yatatāmapi siddhānāṃ kaścinmāṃ vetti tattvataḥ

Among thousands of people, hardly one strives for perfection; and among those who strive and succeed, hardly one knows me in truth.
