Bhagavad Gita Chapter 18, Verse 56

सर्वकर्माण्यपि सदा कुर्वाणो मद्व्यपाश्रयः | मत्प्रसादादवाप्नोति शाश्वतं पदमव्ययम् ||

sarvakarmāṇy api sadā kurvāṇo mad-vyapāśrayaḥ mat-prasādād avāpnoti śāśvataṁ padam avyayam

Even performing all actions always, taking refuge in Me, one attains by My grace the eternal and imperishable abode.

Krishna explains how to attain the eternal abode. 'Sarvakarmāṇy api sadā kurvāṇo mad-vyapāśrayaḥ'—even performing (kurvāṇaḥ) all actions (sarva-karmāṇi) always (sadā), taking refuge in Me (mat-vyapāśrayaḥ). 'Mat-prasādād avāpnoti śāśvataṁ padam avyayam'—by My grace (mat-prasādāt), one attains (avāpnoti) the eternal (śāśvatam) and imperishable (avyayam) abode (padam). This is the key teaching: you can perform all actions, but if you take refuge in Krishna and work for Him, you attain the eternal abode by His grace. You don't need to abandon action—you perform all actions while taking refuge in the Supreme. Through this refuge and His grace, you attain the eternal, imperishable abode. This is the path: perform all actions, take refuge in the Supreme, and attain the eternal abode by His grace.
