Demi is lesser, meaning under to the main or not as powerful, it has no discredit to the being, mearly an inference of some that are or greater power of some nature or an order of hyrachy.
much liek the family unit which has its leader as one or both of th eparents usualy down through the age to the youngest.
i have seen a women devoured by a ball of flame and leave no trace, it was quite bizzar, one could suggest there was some special power at work.
considering the ball of flame was around 15 feet high and around 30 to 50 meters in width and was caused from a gas leak.
there was no trace of her left at all, which does seem rather odd.
one minute standing there screaming
the next minute BOOM i nealy crapped myself and she was gone.
i suspect the actualy temperature to completely incinerate a human body is much greater than such an explosion could achive.
i was about 25 meters away from her side on to the rather masive explosion.
i have witnessed other weird things through life but these things are not always needed tobe explained, life is too short (and love is too far and few between) to dwell on such confounding weirdness.
there is an age old expresion "be carefull what you wish for...".
have you asked yourself how the proof to the question you seek would alter your life ?
what is the changes you would make if it were true or untrue ?
pick one you liek and run with it.
yes or no
it matters little to you unles you accept it with your heart and live it.
so choose one and live that so atleast your doing what you want and having a good time
