Word by word
The verse says
For someone unattached and free, his mind settled in knowing, acting as an offering - everything he does dissolves completely.
In plain words
The summary of the whole argument so far.
Unattached. Free. Mind established in knowing. Acting yajñāya - as offering.
And then the result: samagraṁ pravilīyate - it dissolves entirely. Not reduced. Gone.
Where you've felt this · in friendship
You help a friend move flat and you genuinely wanted nothing back for it. A year on you cannot really remember doing it. He can, and that is the only place it is stored now.
Going deeper
Pravilīyate - melts away, dissolves. The verb is gentle, and it matters that it is not destroyed.
What dissolves is the binding quality of action, not the action. The help was still given. The work still happened. What is absent is the residue - the thing that would have attached to the doer and required collecting later.
Jñānāvasthita-cetasaḥ - whose mind is established in knowing. The word for established means standing firm, settled, and it belongs to the same family as the steady one of 2.54.
And yajñāya ācarataḥ - acting for the sake of offering - brings back the word that 3.9 stretched past the fire altar.
The next seven verses stretch it much further. This verse is the pivot: it states the principle, and then the chapter shows how many different lives it fits.
