Perspectives
"I don't think you can analyze love. It's the greatest mystery of all. No one knows why it happens or doesn't. Love is a chance combination of elements. Any one thing might be enough to keep it from igniting. A mood, a glance, a remark. And if we could define love, predict it, it would probably lose its power."
 - Neelix, 

"Shon-ha'lock, love, is the most dangerous emotion of all. It produces many other emotions. Jealousy, shame, rage, grief. You must learn to suppress them all, otherwise they will consume you."
 - Vulcan Master,
