Bhagavad Gita · Chapter 2: The Path of Understanding
Bhagavad Gita 2.39
एषा तेऽभिहिता सांख्ये बुद्धिर्योगे त्विमां शृणु ।
बुद्ध्यायुक्तो यया पार्थ कर्मबन्धं प्रहास्यसि ॥
eṣā te'bhihitā sāṃkhye buddhiryoge tvimāṃ śṛṇu | buddhyāyukto yayā pārtha karmabandhaṃ prahāsyasi ||
This understanding has been explained to you through analysis (sankhya); now hear it as a practice (yoga). Equipped with it, Arjuna, you will cast off the bondage of action.
Modern context
Krishna marks a change of gear. So far he has given understanding: what the self is. Now he will give practice: how to act. Insight alone seldom changes how we live; it needs a discipline of daily action. The promise is large: a way of working that leaves a person free and not entangled.
