Bhagavad Gita: Chapter 4/Verse 16

किं कर्म किमकर्मेति कवयोऽप्यत्र मोहिताः ।
तत्ते कर्म प्रवक्ष्यामि यज्ज्ञात्वा मोक्ष्यसेऽशुभात् ॥४-१६॥

kiṃ karma kimakarmeti kavayo'pyatra mohitāḥ ।
tatte karma pravakṣyāmi yajjñātvā mokṣyase'śubhāt ॥4-16॥

"What is action? What is inaction" Here, even poets are confused. I shall explain that action to you, which having known, you shall be liberated from unpleasantness.
