The only way to etenal love is to experience it through that which is etenal-and this ain't another human being. Think about it. We constantly try to experience the eternal through a vehical which will one day die.
Actually, trying to experience love without first truly loving yourself is fruitless. Yes you will experience something, and you will probably think it is love. But then it will change and you will say-damn, that wasn't love, it must be over here. And off you go, looking outside for something that can only be experienced inside.
There is absolutly nothing wrong with any of this searching-but it is useless. There is a Sufi story about the Holy-Fool, Nasrudin.
Nasrudin is found by his neighbours searching frantically the ground outside his house. "What are you searching for Nasrudin?" they ask. "My walking stick" he answers, "I left it somewhere in my house." "If you left it in the house," the neighbours ask," why are you looking out here?" Why it is dark in there" he answers "The light is much better out here."
