"endo" was to say "inside", as in "endogenous dmt" (dmt produced within the body).  

"phile", was to say "lover".  

I see hyperspace as going within, going inside.   Higher, and higher orders of dimension which infinitely continue to the center of all being.    This is the "inside" which I love.

"endo" also turns out to be a slang term for cannabis.  I've no disrespect for cannabis, but I don't wish to be associated with cannabis any more than any other plant.
