Here is the Sanskrit anuvad, Hindi anuvad, and English translation of Sankhya Yoga Chapter 2, Verse 2.49.
Sanskrit
दूरेण ह्यवरं कर्म बुद्धियोगाद्धनंजय । बुद्धौ शरणमन्विच्छ कृपणाः फलहेतवः ॥ २.४९ ॥
Hindi
इस समत्वरूप बुद्धियोग से सकाम कर्म अत्यन्त ही निम्न श्रेणी का है। इसलिए हे धनंजय! तू समबुद्धि में ही रक्षा का उपाय ढूँढ अर्थात् बुद्धियोग का ही आश्रय ग्रहण कर क्योंकि फल के हेतु बनने वाले अत्यन्त दीन हैं|
English
The Blessed Lord said unto ARJUNA:When actions are performed by a person for any selfish motive or gain, that person shall always suffer and remain disappointed in life. Those, however, who practice KARMYOGA or the Yoga of even-mindedness, are free from any worries or disappointments for they do not care for the results of their actions and duties.
