The brahma is this earth by fire ruling this world, the past is a repetition of ones doing arjuna for my contempt infact kaunteya, the past life or life of being reborn is not without the attainment of education.
Perhaps there are many adobes, the significance of a brahma bhuval lokah is the physics of which we are here on this earth at this time to do karma. For example the fictitious character Thor had to come to earth to do his karma.
On the word upeksha/upetya to mean contempt made the most sense because there must be relevance also to why brahma (the bearded man) is ruling this world by fire. And also significance to why we are born again, because God the all powerful is unhappy with us and so we are repeating the life for the education we needed to have. It is also what we are accounted for and why Arjuna is referred to as kaunteya.
All the world from the realm of Brahma down to earth are subject to rebirth. But O Arjuna one who has attained to me is never reborn. It is true we are all subject to rebirth. Take a look at my meaning for why we are subject to rebirth. This translation does not accurately explain the Sanskrit verse. Also, reading it from left to right has to make sense. I hope I am able to do that in the way the verse is understood.
