say what?

I love the song Southern Cross by CSN.  Every time it comes up on my IPod I sing along, creating my own nonsensical lyrics.   So I googled it to figure out the words and learned this - nobody seems to know what the hell it's about.  There are chat rooms abuzz about its meaning and long long long lists of internet debates on the subject.  Most people seem to think the song is about finding God.  Or maybe it's about a guy who left his wife for a sea?  What do you think?

Got out of town on a boat
Goin' to Southern islands.
Sailing a reach
Before a followin' sea.
She was makin' for the trades
On the outside,
And the downhill run
To Papeete.
Off the wind on this heading
Lie the Marquesas.
We got eighty feet of the waterline.
Nicely making way.
In a noisy bar in Avalon
I tried to call you.
But on a midnight watch I realized
Why twice you ran away.
Chorus
Think about how many times
I have fallen
Spirits are using me
larger voices callin'.
What heaven brought you and me
Cannot be forgotten.
I have been around the world,
Lookin' for that woman/girl,
Who knows love can endure.
And you know it will.
And you know it will.
When you see the Southern Cross
For the first time
You understand now
Why you came this way
'Cause the truth you might be runnin' from
Is so small.
But it's as big as the promise
The promise of a comin' day.
So I'm sailing for tomorrow
My dreams are a dyin'.
And my love is an anchor tied to you
Tied with a silver chain.
I have my ship
And all her flags are a flyin'
She is all that I have left
And music is her name.
Chorus
Think about how many times
I have fallen
Spirits are using me
larger voices callin'.
What heaven brought you and me
Cannot be forgotten.
I have been around the world,
Lookin' for that woma/girl,
Who knows love can endure.
And you know it will.
And you know it will.
So we cheated and we lied
And we tested
And we never failed to fail
It was the easiest thing to do.
You will survive being bested.
Somebody fine
Will come along
Make me forget about loving you.
At the Southern Cross.

Peace!
