Srimad Bhagavat Gita commentary chapter 8 verse1-2

 Chapter 8 verse 1-2 

“Arjun said: O Supreme Lord, what is Brahman (Absolute Reality), what is adhyātma (the individual soul), and what is karma? What is said to be adhibhūta, and who is said to be Adhidaiva? Who is Adhiyajña in the body and how is He the Adhiyajña? O Krishna, how are You to be known at the time of death by those of steadfast mind?” 

There are 14 lokas in sanatana dharma-7 higher lokas and 7 lower lokas. But all of these lokas still are not the ultimate destination to skip the cycle of birth and death. Arjuna’s question is how to get out of this cycle of birth and death forever. Krishna earlier mentioned that one can get out of the cycle of birth and death by remembering Him at time of death. Arjuna is asking the explanation of both all His attributes and how one can think of Him at the time of death.
