' The Fourth force had a very important
role to play: it had to bring to fruition 
all that the Spirit had imagined.  It 
'inserted' thus, an infinitesimal part of 
the Spirit in the human body.  This 
comprises what you would call the 
Astral body, which forms one ninth of 
the essential human being and 
consists of one ninth of a 'Higher-self' 
which is sometimes called the 
'overself'.  The Higher-self of man is, 
in other words, an entity which sends 
one ninth of itself into a human body,
 becoming the person's Astral being.  
Other physical bodies are inhabited, 
similarly, by other ninths of the same 
Higher-self and yet each part remains 
integral to the central entity.
' Further, the Higher-self is a ninth part
of a superior Higher-self which, in 
turn, is a ninth part of a more superior 
Higher-self. The process continues as 
far back as the source, and allows the 
enormous filtration of spiritual 
experience required by the Spirit.' 

' The Astral body should be either in  a
physical body or with its Higher-self, 
of which it is a part.'
