The written format. One thing to keep in mind is the physical body vibrates around 62 to 70 MHz on physical death it drops to 25 MHz. The spirit is going to be free and therefore should be a higher frequency anyway, but I don’t believe it matters. As long as one is aware and focused on the reality that their intentions are to leave this world and exit the grid. Intentions are everything and you are non physical so everything that you do from then on is thought reactive. That’s how one moves from a to b, think and it is so.
Just a little more info on why we need to exit the matrix of this reality. Read up on the quote by St Paul/Saul, who was a cousin of Jesus.
