In the days when we would stay employed with the same firm for a majority of their career, we would start with an entry level job as a junior accountant, let us say, and work our way up the corporate ladder. Over a period of fifteen or twenty years, that junior accountant could end up being promoted to chief financial officer. At that point, he would no longer be concerned with trivial details such as checking receipts against journal entries and so on. He would focus on bigger issues such as the financial health of the entire company.
 
Similarly, when Shri Krishna provided a long list of Ishvara’s expressions, he wanted to ensure that Arjuna did not get stuck at the level of knowing more and more expressions. He wanted Arjuna to stop asking more questions, take a step back and ask himself a very basic question.
 
If Ishvara is present in everything in the universe, and Ishvara is also present in me, is there anything else in the universe besides Ishvara? In other words, if Ishvara is in everything, isn’t everything in Ishvara ultimately? It is like asking: If there is space in everything including me and including every atom, isn’t everything in space?
 
With this intriguing thought, Shri Krishna concludes the tenth chapter and sets the stage for the eleventh chapter. While the tenth chapter was about how the one Ishvara was in all, the eleventh chapter is about how all is in the one Ishvara.
