Brain is a filtering mechanism. We don’t have to move in space or time. Just tune into different channels to get into past, future, this loka or other loka. There are really recorded incidents of say Rama and Krishna. Rama’s memory is moved into Krishna and Krishna’s memory is moved into Rama. Then Rama becomes Krishna and Krishna becomes Rama. Rama is tuned to Krishna’s memory and Krishna is tuned to Rama’s memory.
-Sri Bhagavan
