There are so many definitions of what true love is, that it boggles my mind. In fact, all one has to do is Google the term itself and your bombarded with a plethora of new age, psychological and physiological attempts to describe something that (in my opinion at least), exceeds definition itself.
If I could borrow a quote from Wedding Crashers, (yes I know...shut it):
True love is your souls recognition of its counterpoint in another.
Now, as much as I hate to say it, Owen Wilson might be onto something here. If we were to accept that love goes beyond just a simple biological function of human procreation, then we would also have to accept that "love" would have to have an ethereal quality about it. Love then, could be nothing but the missing piece of a puzzle which we so eagerly await to be completed.
Perhaps love, is the energy that forms the duality, maybe its the song behind our universe, or maybe its the sticky remnants found in the ally behind the bar.
All I know is that you need to follow your feet and perhaps one day this beautiful mess will clean itself up.
