Bhagavad Gita · Chapter 4: Knowledge and the Renouncing of Action
Bhagavad Gita 4.9
जन्म कर्म च मे दिव्यमेवं यो वेत्ति तत्त्वतः ।
त्यक्त्वा देहं पुनर्जन्म नैति मामेति सोऽर्जुन ॥
janma karma ca me divyamevaṃ yo vetti tattvataḥ | tyaktvā dehaṃ punarjanma naiti māmeti so'rjuna ||
One who truly understands my divine birth and action in this way is not born again on leaving the body. That person comes to me, Arjuna.
Modern context
The promise here is attached to understanding, and the word that matters is tattvatah, 'as it really is'. Knowing the stories of Krishna's life is one thing. Understanding how he can be born while remaining unborn, and act while remaining untouched, is another. Whoever truly sees this has grasped something about their own self as well, and that knowledge is what frees. The verse values insight above information.
