Sanskrit Original
स्वर्णं यथा ग्रावसु हेमकार: क्षेत्रेषु योगैस्तदभिज्ञ आप्नुयात् । क्षेत्रेषु देहेषु तथात्मयोगै- रध्यात्मविद् ब्रह्मगतिं लभेत ॥ २१ ॥
svarṇaṁ yathā grāvasu hema-kāraḥ kṣetreṣu yogais tad-abhijña āpnuyāt kṣetreṣu deheṣu tathātma-yogair adhyātma-vid brahma-gatiṁ labheta
An expert geologist can understand where there is gold and by various processes can extract it from the gold ore. Similarly, a spiritually advanced person can understand how the spiritual particle exists within the body, and thus by cultivating spiritual knowledge he can attain perfection in spiritual life. However, as one who is not expert cannot understand where there is gold, a foolish person who has not cultivated spiritual knowledge cannot understand how the spirit exists within the body.
