B.G 4.15

एवं ज्ञात्वा कृतं कर्म पूर्वैरपि मुमुक्षुभिः। कुरु कर्मैव तस्मात्त्वं पूर्वैः पूर्वतरं कृतम् ॥१५॥

evaṁ jñātvā kr̥taṁ karma pūrvairapi mumukṣubhiḥ। kuru karmaiva tasmāttvaṁ pūrvaiḥ pūrvataraṁ kr̥tam ॥15॥

[एवं ज्ञात्वा कृतं कर्म पूर्वैः अपि मुमुक्षुभिः। कुरु कर्म एव तस्मात् त्वं पूर्वैः पूर्वतरं कृतम्॥
evaṁ = thus; jñātvā = knowing; kr̥taṁ = done; karma = actions; pūrvaiḥ = by previous; api = also/even; mumukṣubhiḥ = seekers of liberation;। kuru = perform; karma = action; eva = only; tasmāt = therefore; tvaṁ = you; pūrvaiḥ = by previous / by ancestors; pūrvataraṁ = pocessing the similar attitude as previous; kr̥tam = done;॥]

(Understanding Me) thus, knowing the actions done by previous seekers of liberation, you also perform such actions only, possessing the similar attitude as previously possessed by your ancestors.
