अनाश्रितः कर्मफलं कार्यं कर्म करोति यः।स संन्यासी च योगी च न निरग्निर्न चाक्रियः॥
anāśritaḥ karma-phalaṃ kāryaṃ karma karoti yaḥsa sannyāsī ca yogī ca na niragnir na cākriyaḥ
Word by word
The verse says
Krishna said: Whoever does the work that has to be done without leaning on what it will fetch — he is the renouncer and he is the practitioner. Not the man without ritual fires, and not the man without duties.
In plain words
The chapter opens by taking a title away from two people.
Niragniḥ — without fires. Akriyaḥ — without duties. Both were recognised religious positions.
And both are told, in the first line of the chapter, that the name belongs to somebody else.
Where you've felt this · at work
The man who actually keeps your office running never sends a message about keeping the office running. The colleague who talks most about how hard he works leaves at four. From outside you would put those two the wrong way round.
Going deeper
Titles are being reassigned here, and it is worth seeing how direct it is.
In Arjuna's world, giving up the household fires was a formal step with a formal name. So was giving up prescribed rites. Both marked you publicly as having renounced.
Krishna says neither one makes you a renouncer. The person who does the work in front of him without leaning on the outcome is the renouncer — and, in the same breath, the practitioner.
That collapses the fork Arjuna raised at the start of Chapter 5 by refusing to keep the two words apart. They now name one person.
And the test has moved somewhere unverifiable from outside. You can see whether a man has let his fires go out. You cannot see what he is leaning on, which means this is not a status anybody can be awarded.
