Open the full passageसाङ्ख्ययोगौ पृथग्बालाः प्रवदन्ति न पण्डिताः । एकमप्यास्थितः सम्यगुभयोर्विन्दते फलम् ॥४॥
Sanskrit
sāṅkhya-yogau pṛthag bālāḥ pravadanti na paṇḍitāḥ ekam apy āsthitaḥ samyag ubhayor vindate phalam
Translation
Only the ignorant speak of devotional service [karma-yoga] as being different from the analytical study of the material world [Sāṅkhya]. Those who are actually learned say that he who applies himself well to one of these paths achieves the results of both.
