What is Love?

What is love? Is it just a feeling, a thought, an action, or is it all of it? Has anyone figured out how to explain love? How to put it into words so that someone can understand what “love” consists of? How do we muttle through if one person’s version of “love” is different than the other? Can these two co-exist with each other, or is it just an affair doomed from the start? Even the most perfectly matched pair seems to fall if the version of “love” is not matched correctly. How do we know which love is right or wrong, or is all love right and we just have to learn to accept within ourselves the version of “love” that is right for us and handle the pain when we realize it is not with whom we thought.
