What will be the status of the jIvAtmA at Srivaikuntham after attaining moksham? How will be our body? How will be our knowledge? Will we be called by the name given to us by our parents on Earth? In addition to Perumal, Thayar and Nityasuri-s, will we be able to worship Azhwars and Acharyas? Can we converse with them in Tamil?

After attaining moksham, we will not have the same physical body that we have here; we can take a new physical body at Srivakuntham which will be devoid of all the defects of the physical body on Earth; it will be a divine body and is called ‘aprAkruta’ (an extraordinary body not made of 5 elements).
We will have knowledge that will enable us to know everything i.e. we become omniscient. Before attaining moksham, our knowledge is diminished due to our karma; at Srivaikuntham, as the effects of both good and bad deeds are removed, we will have undiminished knowledge.
There is no need for us to have the same name we have on Earth; we will not have the same name.
We worship Perumal, Thayar, Nityasuri-s, Azhwars, and Acharyas; we can talk to all of them. We can talk to them in Tamil. Svami Desikan has said we can recite stotras in Tamil at Srivaikuntham – “pallANDE pallANDum pADuvOmE”.
