“Without you I am nothing.” 
Have you ever said this to another? 
Then this other somehow made you feel whole and complete.  And what if that one departs from your
life?  Does that mean you are no longer
whole?  You may feel this way, but that
is only the false perception of being human. 
As a human, when you remain in this mind-set, you are correct.  You are incomplete.  How do you become whole?  By realizing that you are a
spirit-being.  You are a “spirit being
human.”  When you are feeling incomplete,
shift your awareness to the part of you that is always with you, the basic essence
of your Greater Self, which is of Spirit. 
Align the human with the Spirit and then you experience a love and
completeness far greater than that of coupling with another human being.  Realize who and what you are and step into
the fullness of your magnificence.  You
are whole and complete now.
