Word by word
The verse says
Some pour hearing and the other senses into the fire of restraint. Others pour sound and the other objects into the fire of the senses.
In plain words
Two opposite practices, described in the same terms.
One: put the senses into the fire of restraint. Hold them back.
Two: put the objects into the fire of the senses. Let contact happen and let it burn there.
Where you've felt this · in sport
One athlete cuts everything out for the season. Another keeps the ordinary life and simply trains through it. Both arrive in condition and neither could do it the other way.
Going deeper
The pairing here is more interesting than it first looks, because the two practices are opposites and both are approved.
The first is withdrawal — the tortoise of 2.58. The second is the opposite: the senses meet their objects, and the meeting itself is the offering. That is 2.64's person moving among things with the pull and push gone.
The Gita has been holding both since Chapter 2 without resolving them, and here it simply lists them side by side as two fires.
Which is the honest position. Some temperaments do better with abstention and some with engagement, and the text declines to say which is right.
What both have in common is the structure: something is being given up rather than kept. In the first case the sense is surrendered. In the second the object is. Neither is being accumulated, and that is what makes both of them yajña.
