sanity is a reletive subject but Love (getting back to the point of the thread) is not rational, scientific or quantifiable. it is an untangable thing that only a few understand and even less find. It is impossible to completly explain why it does what it does to normal grounded people but it is one of the God given wonders of being a human being with soul, compassion, charity and indeed, love. It is not to be explained. You either have it in your life or you do not. You cannot invite it in or for that matter decide to banish it. Love will crash through the door without invitation. One day, it will demand your attention. On that day, just as the same sun melts the snow and hardens the clay, it will either soften or harden your heart. If you are lucky, you will have a choice as to which. For most of us, it will decide for you. When that day comes, be ready and enjoy your moment of life and realise you are a person, not mearly another animal that breaths and functions but a soul and a spirit. Enjoy Love for it's ability to show you who and what you are.
