4.15
एवं ज्ञात्वा कृतं कर्म पूर्वैरपि मुमुक्षुभिः | कुरु कर्मैव तस्मात्त्वं पूर्वैः पूर्वतरं कृतम् ||१५||
evaṁ jñātvā kṛtaṁ karma pūrvair api mumukṣhubhiḥ kuru karmaiva tasmāt tvaṁ pūrvaiḥ pūrvataraṁ kṛtam
Translation
All the liberated souls in ancient times acted with this understanding of My transcendental nature. Therefore, as the ancients, perform your duty in this divine consciousness.
Interpretation
The ancient seekers of liberation ('mumukṣhu' — those who desire liberation) performed their duties with the understanding of the divine's transcendental nature. Arjuna is being invited to join this ancient lineage of karma yogis — to perform his duty in the same spirit of divine understanding.
