Book Of Days Lyrics
One day, one night, one moment
My dreams could be tomorrow
One step, one fall, one falter
East or west, over earth or by ocean
One way to be my journey
This way could be my book of days
Ó lá go lá, mo thuras
An bealach fada romham
Ó oíche go hoíche, mo thuras
Na scéalta nach mbeidh a choích
No day, no night, no moment
Can hold me back from trying
I'll flag, I'll fall, I'll falter
I'll find my day maybe
Far and away
Far and away
One day, one light, one moment
With a dream to believe in
One step, one fall, one falter
And a new world across a wide ocean
This way became my journey
This day ends together
Far and away
This day ends together
Far and away
Far and away

It means to keep trying no matter what, and to be brave to get through the journeys and rocky roads of life.

She is going somewhere; a journey obviously, full of the next morning and the way the sun shines on the ocean, because in my mind, she is going on a voyage of sorts. it could be a metaphor, a young woman growing up, breaking out oif the confinements of a teenager, voicing herself, finding herself, and keeping track of it in a "Book of Days"
Commentations by Boomlily's friend waterbaby

I agree with Myoria and boomlily55, and I also have a little different spin on this song. Some time ago perhaps 6 - 7 years ago I heard second hand that some christian clergymen believe that Enya's work is an introduction to Buddhism. I have an informational book titled "Essential Buddhism" and learned that one of the most important parts of Buddhism is meditation, of "being in the moment". This would also match with the line :
One day, one night, one moment
In some forms of meditation, the purpose is to attain Nirvana
If you go out on a limb this could be the lines
My dreams could be tomorrow as well as I'll find my day maybe Far and Away
Other similarities to Buddhism: Enya's music can be said to be overall very peaceful, her lyrics are removed from what is commonplace.
I saw a video in which Enya was playing on the piano for this song, and she was dressed in white and there were flowers scattered all around. Maybe a coincidence or maybe not, but some if not all buddhists have flowers present in the place where they meditate.
If I am wrong in my remarks, I would appreciate if someone corrected me, because I too would like to learn something new.

I love this song! It's so pretty! They played this music in the background of the theatrical trailer for the movie Tuck Everlasting. That's when I first heard it:)

I agree with all of you guys. I say all of the above. I know the Irish Gaelic version by heart. Does anybody here know what the title for "Book of Days" is in Irish Gaelic? If so, please most in my messages. Merci. I love this song so much! Yee-haw! Very beautiful song. Is it correct that Enya composes and writes the lyrics to the songs that she sings by herself?

After first verse (elyrics.net): Ó lá go lá, mo thuras, an bealach fada romham. Ó oÃche go hoÃche, mo thuras, na scéalta nach mbeidh a choÃch.
Translation (imtranslator.net): Day by day, my journey, The long pilgrimage before me. From night to night, my journey, The stories that will never be again.
Composer credit for Enya's songs (allmusic.com): Enya, Roma Ryan and (rarely) Nicky Ryan

You are right myoria
