Bhagavad Gita · Chapter 5: Renunciation in Action
Bhagavad Gita 5.4
सांख्ययोगौ पृथग्बालाः प्रवदन्ति न पण्डिताः ।
एकमप्यास्थितः सम्यगुभयोर्विन्दते फलम् ॥
sāṃkhyayogau pṛthagbālāḥ pravadanti na paṇḍitāḥ | ekamapyāsthitaḥ samyagubhayorvindate phalam ||
It is the immature, not the wise, who speak of knowledge and yoga as different things. One who is properly established in even one of them gains the fruit of both.
Modern context
It is the immature who set the path of understanding against the path of practice. The same quarrel appears everywhere: theory against practice, thinkers against doers, study against experience. Krishna says that whoever follows either one properly gains the result of both, because each, taken seriously, leads into the other. Real understanding changes how one acts, and sincere practice produces understanding.
