Word by word
The verse says
Whoever does my work, who holds me highest, who is devoted to me, free of attachment, without enmity toward any being — that person comes to me, Arjuna.
In plain words
Five things, and the last one is the one to notice.
Nirvairaḥ sarva-bhūteṣu — without enmity toward any being.
It is said to a man who has just been told to fight, by somebody who named the people he will have to kill.
Where you've felt this · in community
A good referee can send a player off and shake his hand afterwards, and mean both. He is not pretending the foul did not happen. He has simply never confused doing his job with having something against anybody.
Going deeper
Ending the most terrifying chapter in the book on the absence of enmity is the most demanding instruction in it.
Arjuna has been shown a war and told to fight it. The final line of the chapter asks him to do that without hatred toward anyone involved. Those are not easy to hold together, and the text does not pretend they are — it simply puts them in the same sentence and stops.
The traditions have found this difficult, and honest readers should. A verse that permits fighting without enmity can be used to excuse a great deal, and has been.
What is clear is what the chapter has put in the way of that misuse. The man receiving this instruction has just spent fifty verses in terror, has wept, has apologised to his friend, and has been told that none of it was his doing. Nobody arriving at this verse through that chapter could mistake it for permission to fight gladly. It is the opposite: the hardest possible description of what acting well costs.
