What is the spirit scientifically?
gpt
there is a pattern of neuronal synaptic firing.
this pattern is determined by a thought.
the synaptic firing generates an electro-magnetic field.
the electro-magnetic field is also in a similar pattern to the thought.
this field could be considered mind.
the manner in which it is used could be called spirit.

a thought could be beneficial or detrimental.
in common terms, good or evil.
in mysti-speak, angelic or demonic.

example:
'Everyone seems to be in good spirits today'
'Go with the spirit of god my child'

initiating thoughts and response thoughts can be conditioned by external sources.
this is where the concept of 'being responsible for all of self' is lost.
it allows a faux reassignment of responsibility to an external source.
i.e. one part of the idea of possession by a evil spirit
and because of this a whole narrative has been created around it in many variations.

in short, the quality of spirit can either be determined by the individual or by an external source.
to reach the highest degree of growth attainable, self determination is required.

hope this helps.
best wishes.

The field extends beyond the body. 

There is no reason to believe that some people cannot perceive it. We know some people (mainly women) can see further into the UV spectrum of light. That ability would be absolutely terrifyingly powerful in pre-modern times. Less so now with artificial lighting.

Is there a way to gain this ability?
