There was once a boy who from childhood felt
he had unfinished business;
he was never certain what it was,
and after reaching the years of physical maturity,
and leaving home,
he returned to seek his father’s response regarding 
the always present sensation of there being 
some unsettled affair in his life
The son noted that he continued to feel a 
non-physical frustration with life, and had studied 
several teachings whose verbally described interest, 
and goal superficially appeared to match his, but 
none of which ever resulted in conclusive satisfaction.
The father nodded his understanding of 
the younger’s words, and said:
 “As you now obviously know from reading,
there have always been people who experienced 
this particular feeling of inner disquiet,
and after attempts to describe it to others, 
which was met with either 
incomprehension, or disinterest,
they commonly concluded that what they were
experiencing was so unusual as to be perhaps, 
even supernatural.
One thing was for certain: the vast majority of humanity, through neither their words, nor activities,
evidenced any apparent experience of this
feeling that there is some sort of 
‘unfinished-business-about-man,'
(other than for weakened, impractical reflections of it 
that came to be found in collectively accepted ideas 
that there actually is a supernatural world beyond the
sensual one in which man presently lives;
such variations, offering no solution to the problem
as it is consciously suffered by the few.)
Those with this direct disquiet must come to the personal realization that the sensation is not dependent on
external circumstances,
but is a totally self-contained, inner event,
and they must further be free of any notion that it is
supernatural, or ‘spiritual,’ in the sense of it being 
too vague to ever be understood.
For a person experiencing what you are my son,
to ever even start looking into the matter properly,
he must recognize plainly that the entire affair is occurring in his brain.
This is very hard to do, and few accomplish it.
But there is something even more difficult after that.
The brain is the central processor,
consciously and otherwise, of all information concerning man’s external and internal worlds;
this feature of the brain is plain,
but what is not  so obvious, 
and which is at the very root of the unsettled feeling 
you come asking about,
is that the brain is also engaged in the attempt to
consciously process information about its own operation. 
No one is satisfied to ride the Number 7 bus,
if they await Number 8.
On some routes there is no Number 8 yet."
