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.

In the previous shloka, we saw that repressing our urges and giving up actions does not work. A different approach is needed to clean our vasanaas and selfish desires. In this shloka, Shri Krishna says that we should not give up actions - instead, we should give up attachment.
 
Giving up attachment is a technique unto itself, and this chapter goes into a lot of detail on that topic. To begin with, this shloka informs us that we need to arm ourselves with two weapons: discrimination or "viveka", and dispassion or "vairagya".
 
Let first look at discrimination. If we have followed the teaching so far, we know that material objects are are temporary and are not the true sources of happiness. But it is extremely easy to forget this teaching, especially if we have strong vasanaas and desires.
 
Therefore, we have to constantly arm ourselves with the weapon of discrimination by being always aware and alert about our thoughts and emotions. And we have to be especially alert when we are around objects that we are attached to. For a simple example take food: it could be chocolates for the sweet tooth person, fried food for the obese person etc.
 
Next comes dispassion. If we constantly practice discrimination, dispassion will happen automatically. Objects, people and situations will begin to lose their hold on us. Dispassion will prevent our energy from rushing out into the world of material objects through our senses. This is what the shloka means by the phrase "one who controls his senses by his mind."
 
Finally, once the mind has gained back control over the senses, then the energy that once rushed out through our senses can be channeled into performing karmayoga. The next shloka will go deeper into what Shri Krishna means by karmayoga.
