Bhagavad Gita 4.16

किं कर्म किमकर्मेति कवयोऽप्यत्र मोहिता: ।
तत्ते कर्म प्रवक्ष्यामि यज्ज्ञात्वा मोक्ष्यसेऽशुभात्  ॥

kiṃ karma kim-akarmeti kavayo’py-atra mohitā:
tat-te karma pravakṣyāmi yaj-jñātvā mokṣyase’śubhāt – 4.16

Even the wise ones are confused about what constitutes right action, and what does not. Therefore, I shall tell you what is verily an action, by knowing which you will be free from the inauspicious effects thereof.
