IIH and Meditation

["magesmail" <magesmail@...>]

Hi all,
I am "almost there" with Step 1 and at this juncture i would like 
some clarificationon what "mediattion " means within the context of 
IIH .
At various points in IIH,Bardon says , in effect "meditate on... X". 
So how does one "meditate" ? is it by manitaining an unwavering focus 
on the thought/image /idea to the exclusion of ALL thought (iow , 
with the thought/image etc "fillin" one's consciousness ) or is it 
more a "think about" the focus as in the mental work of step 1, where 
as soonas one has managed 10 minutes of "watching", one learns to 
selectively "think about" a focus ?

Thanks in advance, NKKA
