Here, Shri Krishna offers a guideline for Arjuna in regards to working with other people. He says that one who is working with the attitude of karmayoga should learn to work in harmony with others who may have not yet understood or learned that technique. In other words, Shri Krishna warns us from adopting a "holier-than-thou" attitude with others when performing action.
 
For instance, imagine a little girl playing by herself, and pretending to make tea in a small cup. She brings an empty cup to her aunt and asks her to drink that tea. The aunt should enjoy that fake tea, not start questioning the reality of that team. There is no need to do so, the child is doing what is appropriate. Similarly, just because one is studying karmayoga does not make him or her eligible to behave differently with others.
 
Now, most of our actions are either performed individually or in a team. If we are performing actions individually, it is very straightforward to adopt the attitude of karmayoga. If we are working in a team, we could be playing the role of peers, leaders or followers. In all three of these situations, Shri Krishna urges us to maintain the attitude of karmayoga regardless of whether our peers, leaders or followers have the very same attitude. Their attitude in no way should impact the efficiency of our work.
 
This "live and let live" approach is extremely practical and sensible. But is there a reason behind it? Shri Krishna will explain in the next verse.

Having provided the rationale for karmayoga, Shri Krishna began to provide examples of individuals who gained liberation through karmayoga. He wanted to demonstrate that it indeed was the right path to follow. Providing an example would also eliminate any doubt in Arjuna's mind that karmayoga was a proven methodology, not a new invention.
 
The first example that Shri Krishna provided was that of king Janaka, an apt example since he was a warrior just like Arjuna. Many of us familiar with the Ramayana epic would recognize the name Janaka as the father of Sita, and the king of the Videha kingdom. But the word Janaka here is a post or a title. It refers to any king that was appointed to the throne because of his non-attachment to all material objects, even to his body. This is apparent in the word meaning of Videha which is "one who has given up identification with his body".
 
Why would a kingdom appoint a king that has given up attachments? It is because someone without any attachment would make the most fair, rational and unbiased decisions in favour of the kingdom. He would not come under the sway of emotion or prejudice of any kind. Such kings were known to be excellent administrators. In addition, they were also perfect karmayogis, i.e. they were "sthitha-prajna" or men of perfect wisdom.
 
With this example, Shri Krishna also assured Arjuna that it was perfectly possible to attain the ultimate goal of realization, yet be working in this world. Arjuna did not need to run away from the war or his responsibilities at all.
