The middle self is our everyday ordinary conscious
self, the person we think we are. My understanding is that in order to
make contact with the high self (over soul) which is the part of us that is able
to communicate with spirits that are dead or in other dimensions we must first
make contact with our lower self first (perhaps dead is a bad word as we never
really die anyway).
The Lower self is that part of us that is referred to as the
child within. It is our closest friend to the earth and it is this part of
our self which is able to connect to the earth spirits and divas, wind spirits,
and so on.
according to the Huna we will never be able to make contact
with our high self until we have a working relationship with our low self.
It is the low self who decides when we are ready to put the trinity all together
to make contact with the high self. Pagans, Shamans, Druids, and Wicca all
work with nature and of course the low self. A pendulum, for example can
be a tool to connect to your low self when used correctly. When I do
muscle testing with someone to find out about a physical problem, it is the
lower self that provides the answer through the testing and not the higher self
as some may think.
