Bhagavad Gita Chapter 5, Verse 4

साङ्ख्ययोगौ पृथग्बालाः प्रवदन्ति न पण्डिताः | एकमप्यास्थितः सम्यगुभयोर्विन्दते फलम् ||

sāṅkhya-yogau pṛthag bālāḥ pravadanti na paṇḍitāḥ ekam apy āsthitaḥ samyag ubhayor vindate phalam

Only the ignorant speak of Sankhya (knowledge) and Yoga (action) as different. The wise do not. One who is established even in one attains the result of both.

Krishna clarifies that only the ignorant (bālāḥ) see Sankhya (knowledge) and Yoga (action) as different (pṛthak). The wise (paṇḍitāḥ) understand they lead to the same goal. The key insight: one who is properly established (samyak āsthitaḥ) in even one path attains the result (phalam) of both. This means knowledge and action aren't separate—they're two aspects of the same path. When you act with knowledge, you're practicing both. When you understand the nature of action, knowledge and action unite. The ignorant see them as contradictory—the wise see them as complementary.
