It is our Souls that make us human on Earth.
But without our bodies we are no longer Homo Sapiens.
The soul has such majesty that it is beyond description.
I tend to think of souls as intelligent light forms of energy.

Right after death, souls suddenly feel different because
they are no longer encumbered by a temporary host body
with a brain and a central nervous system.
Some take longer to adjust than others.
