> You have a right to perform your prescribed duty, but you are not entitled to the fruits of action.
> stick to your lane and don't complain. I.e. the caste system
That verse is quite famous and the general interpretation as I understand is this.
You have control on your actions but not on its results. The results depend not only on your actions but on many other factors outside of your control.
Now, one can interpret that it is instruction to "stay in your lane", but I have not seen that interpretation so far in my life in India.
you realize that the caste system that currently exists is completely different from what it was conceptualized as right? you most certainly want to read the conversation between yudhistra and nahusha that talks about caste https://vedabase.io/en/library/mbk/1/30/
So, "have a go, do you best, shit happens, don't worry about it".
