And so it is that in the moment you pledge your highest love, you greet your greatest fear.

All human actions are motivated at their deepest level by one of two emotions-- fear or love.  In truth, there are only two emotions-- only two words in the language of the soul.  Without these two points, without these two ideas about things, no other idea could exist.  Think on this deeply and you will see that it is true.  For these are simply versions, different twists on the same theme.  

There is no other human motivation.  All action is either a thought of love or fear.  It is the first thought.  It is the energy that drives the engine of human experience.  And that is how human behavior produces repeat experience after repeat experience; it is why humans love, then destroy, then love again.  Love sponsors fear sponsors love sponsors fear. . .

Fear is the energy which contracts, closes down, draws in, runs, hides, hoards, harms. 
Love is the energy which expands, opens up, sends out, stays, reveals, shares, heals.  

Fear wraps our bodies in clothing, love allows us to stand naked.  Fear clings to and clutches all that we have, love gives all that we have away.  Fear holds close, love holds dear.  Fear grasps, love lets go.  Fear rankles, love soothes.  Fear attacks, love amends.  

You may be afraid of love.  You've learned the hard way, you tell yourself.  You will be damned if you leave yourself to stand vulnerable again.  But yet the truth is, you will be damned if you don't.
