possessives

["Mr Ekted" <mr_ekted@hotmail.com>]

Hi all, trying to get back into lojban after taking a long break. I am
curious about pe, po, po'e. There seems to be some room for idiom in
their descriptions in the level0 book. Does the word "possession"
really mean ownership, or is it intended to simply mean association?
My hair will always be my hair, but if I cut it off and give it to
you, it is now "also" your hair by possession. How do you specify the
difference? Also:

my country

If you used po'e, does this specifically say "you ARE the country", or
can it mean a lifelong loyalty/nationalism?

my soul

If you use po, does it imply that you feel you can lose your soul, as
opposed to po'e?

Also, ising using pe considered appropriate in all cases when po/po'e
are more appropriate, without any notions of insult?
