Bhagwad Gita
Chapter 12, Verse 12
श्रेयो हि ज्ञानमभ्यासाज्ज्ञानाद्ध्यानं विशिष्यते।ध्यानात्कर्मफलत्यागस्त्यागाच्छान्तिरनन्तरम्।।12.12।।
If you cannot take to this practice, then engage yourself in the cultivation of knowledge. Better than knowledge, however, is meditation, and better than meditation is renunciation of the fruits of action, for by such renunciation one can attain peace of mind.
