To evolve our consciousness, we must
first realize and accept that we are
souls incarnated in physical bodies.  
By thinking that we are only physical
beings we are limiting our own
potential and more importantly, we are
limiting the evolution of our
consciousness.  As the saying goes,
"Think outside the box" as in think
beyond the physical.

We must identify ourselves as souls.  
It's true we have this physical body,
but it is nothing but a vehicle or a
container.  More accurately the
physical body is a medium for us to
experience and learn and evolve.  
It is a tool for us to use wisely for the
evolution of our consciousness or
spiritual evolution.  For example, we
drive our cars to work or get to places.  
It is a tool or medium of transportation.  
However we don't say the car is who
we are.  If the car breaks down, we get
a new one.  Just like the physical body
will one day die and our soul incarnate
into a new physical body (through
reincarnation).  So it does not make
sense to think of ourselves as the tool
or medium or equipment we use.

To know our true identity as souls, we
must also acts as souls.  For example,
if you are a fireman, you perform the
duties or responsibilities of a fireman,
so you act appropriately and
accordingly.  Since all of our true
identity are souls, then we should all
act as souls, think of ourselves as
souls.  The physical body is only a
temporary medium, so all things in the
physical world are also temporary
mediums and tools.  Identify with the
permanent, not the temporary.  
If something is temporary then it is not
us, because if it is truly us, then it
should be permanent.
