There is such an interpretation of the meaning of the title: The song’s about a woman who climbs a mountain at the end of a love affair, sees her reflection in the mountains covered with snow, and becomes less afraid. In the text, the heroine directly asks: what is love?

When I hear this it seems to be about the end of a love relationship from long ago that still meant a lot the narrator.

I have to add my own vote of awesomeness for the imagery in the lines:

"I turned around and the water was closing all around Like a glove Like the love that had finally found me"

To me the image of water closing all around is one of impending disaster - that you're about to be engulfed by waves or floods...and then saying like a glove - meaning that the heartbreak fits him like a glove, as did seemingly this love that had finally found him...only to end, sadly.

The lines:

"How the faces of love have changed turning the pages And I have changed, oh, but you, you remain ageless"

..also speak to this interpretation quite strongly - the faces of love changing meaning moving on and becoming involved with different lovers as time passes. I have changed and you remain ageless is talking about how a memory of somebody doesn't age, even though we do.

Being driven through a "crystal-like and clear-water fountain" and the whole "then I knew" speaks to a kind of clarity and realization about the relationship...and "through the mountains" can be interpreted as through difficult and rocky terrain emotionally, finally "to the sea" which as rivers all flow to the sea is generally a sense of finality and resolution.

It's a pretty sad song in that light...espcially when you can relate to it, as I'm sure most people of a certain age probably can...?
