Bhagavad Gita 12.12

श्रेयो हि ज्ञानमभ्यासाज्ज्ञानाद्ध्यानं विशिष्यते ।
ध्यानात्कर्मफलत्यागस्त्यागाच्छान्तिरनन्तरम् ॥

śreyo hi jñānam-abhyāsājjñānād-dhyānaṃ viśiṣyate
dhyānāt-karma-phala-tyāgas-tyāgācchāntir-anantaram – 12

Knowledge is surely better than practice, and meditative introspection excels mere knowledge. From such reflective meditation, dawns renunciation of the (internal) results of action, and from such relinquishment follows peace.
