Bhagavad Gita 7.3

Among thousands of men, scarcely one strives for perfection, and even among those who gain occult powers, perhaps only one knows me in truth.

मनुष्याणां सहस्रेषु कश्िचद्यतति सिद्धये।
यततामपि सिद्धानां कश्िचन्मां वेत्ति तत्त्वतः॥

manuṣyāṇāṃ sahasreṣu kaśicadyatati siddhaye|
yatatāmapi siddhānāṃ kaśicanmāṃ vetti tattvataḥ||
