I've never really given the direction much thought, sooo I'll stick with my old 'spoon fed' belief that we use in common reference, 'when you die, your spirit goes up (or down)'

This morning I have a 'thought' that it may be that, when a person dies their spirit goes out of their body and then like dropping a drop of dye in water their spirit enters into the spirit realm.'

However, in 15 minutes, I could change my mind...

I also think that quantum physics will discover a portal to the otherside eventually.

So, for now, I plead my ignorance and bow to the more 'learnered minds' as to the directions on how to get there...
