Bhagavad Gita 3.20
Karma Yoga
कर्मणैव हि संसिद्धिमास्थिता जनकादयः | लोकसंग्रहमेवापि संपश्यन्कर्तुमर्हसि ||
karmaṇaiva hi sansiddhim āsthitā janakādayaḥ loka-saṅgraham evāpi sampaśhyan kartum arhasi
English
Kings such as Janaka and others attained perfection of self-realization by performance of prescribed duties. Therefore, just for the sake of educating the people in general, you should perform your work.
हिन्दी
जनक आदि ने केवल कर्म द्वारा ही सिद्धि को प्राप्त किया था। लोकसंग्रह (समाज का कल्याण) भी देखकर तुम्हें करना चाहिए।
