Jai-Vijay were dwelling in Vaikuntha with Lord Vishnu who happened to be born again due to curse by KumAras. Vaikuntha is said to be the final destination by many philosophies. But if that is the final destination, why they happened to be born again considering any reason. (even curse)
So, Is Vaikuntha a temporarily place? Or in other words, is there no guarantee one won't born again even after attaining Vaikuntha?
