When you die, i.e. your consciousness/lifeforce (or soul

) leaves the body then that person is dead
in terms of this dimension. It don't mean that the consciousness is dead/obliterated, but that it is no longer
manifest within this reality!
As to where the consciousness goes on leaving the carcass, no one in this dimension knows.
However if we accept the earth to be approximately 4billion years old, and the universe is suppose to be 13-17
billion years old, then I ask myself where was I before I was born? Again no one knows where my consciousness
was residing until the time of my manifestation (via the womb).
Therefore I have to assume that when the time comes and I leave this reality
I may probably go back to whence I came, from the great infinity.
But who knows!!!
