There have been references about divine abodes of vaikuntha in Vishnu puran and Bhgavadam,does vaikuntha really exixts at first place ,if so what will be the day to day activities of vaikuntha vaasis ? Do they have time concept there ? Will they see Sriman Narayana daily ?
No such lokas exist as references to Vaikuntha do not exist in Rig Veda, which is the source for every spiritual aspect of Sanatana Dharma aka Hinduism.
Sri Ramana Maharshi was considered to be a great sage of his times. An excerpt from his teachings.
Similarly someone enquired of Bhagavan some time back, “People talk of Vaikunta, Kailasa, Indraloka, Chandraloka, etc. Do they really exist?”
Bhagavan replied, “Certainly. You can rest assured that they all exist. There also a Swami like me will be found seated on a couch and disciples will also be seated around him. They will ask something and he will say something in reply. Everything will be more or less like this. What of that?
If one sees Chandraloka, he will ask for Indraloka, and after Indraloka, Vaikunta and after Vaikunta, Kailasa, and so on, and the mind goes on wandering. Where is shanti? If shanti is required, the only correct method of securing it is by Self-enquiry. Through Self-enquiry Self- realisation is possible.
If one realises the Self, one can see all these worlds within one’s self. The source of everything is one’s own Self, and if one realises the Self, one will not find anything different from the Self. Then these questions will not arise.
There may or may not be a Vaikunta or a Kailasa but it is a fact that you are here, isn’t it? How are you here? Where are you? After you know about these things, you can think of all those worlds.”
