दूरेण ह्यवरं कर्म बुद्धियोगाद्धनञ्जय। बुद्धौ शरणमन्विच्छ कृपणाः फलहेतवः ॥

dūreṇa hy-avaraṁ karma buddhi-yogād dhanañjaya buddhau śharaṇam anvichchha kṛipaṇāḥ phala-hetavaḥ

Far lower than the Yoga of Discrimination is action, O Dhananjaya. Take thou refuge in the Pure Reason; pitiable are they who work for fruit.

In plain words: Krishna says action done for reward is far lower than action guided by wisdom. He tells Arjuna to rely on clear understanding, because people who work only for rewards are to be pitied.
