य एवं वेत्ति पुरुषं प्रकृतिं च गुणैःसह।सर्वथा वर्तमानोऽपि न स भूयोऽभिजायते॥
ya evaṃ vetti puruṣaṃ prakṛtiṃ ca guṇaiḥ sahasarvathā vartamāno ’pi na sa bhūyo ’bhijāyate
Word by word
The verse says
Whoever knows the person and nature along with the strands in this way is not born again, however he happens to be living.
In plain words
The last clause is the surprise.
Sarvathā vartamāno 'pi — however he is living. In whatever way, in whatever place.
No special life is called for. No job, no rank, no setting. Knowing it does not wait on any of that.
Where you've felt this · in failure
You finally understand why you keep ending up in the same argument with your brother. Nothing in your life changes that week. Same job, same flat, same brother. The next time it starts you can see it starting, and that is the whole difference.
Going deeper
Attaching no lifestyle conditions to this is a deliberate omission, and the surrounding literature makes it conspicuous.
Much of the tradition this chapter draws on assumed that liberating knowledge required a particular situation: renunciation, a teacher, a forest, celibacy, freedom from obligations. This verse says however he is living. Arjuna, who is about to fight a war, is the proof the text has chosen.
That is consistent with Chapter 12's ladder, which kept lowering the requirement until it reached somewhere anybody could stand.
What it rules out is the most common reason people postpone this. The conditions are never going to be right — there will always be the job, the family, the year that is not the year for it. The verse removes that as a factor, which is encouraging and also takes away the excuse.
