You are love embodied. 
Yes, love is an emotion.  It is
something you experience and it is something you give, but it is also what you
are.  This is why you know it when you
feel it.  It is why you feel out of sorts
when you withhold it or express anything less. 
Love is your very nature, nothing less. 
Do you feel out of balance?  Sit
quietly and focus on the heart, the central part of you wherein love
resides.  Allow that essential part of
you to flow outward, bringing the rest of “you” back into alignment, and then
allow it to flow outward into the world, bringing you back into alignment with
All That Is.  At times this takes an act
of will when you have allowed yourself to become so unbalanced that you do not
feel the love, but it is always there, just as you will always be … Love.
