Analysis of A thousand year old light

Sitting under the stars, wondering about the afars
Shining brighter than a thousand suns, playing with love like guns
My sparkle, fired, my attempts, tired
Raced with thoughts of when, regretting I didn't speak there and then
Dreams of our hands, tied together like festival wrist-bands
Your unaccompanied love freeing like a great war dove
Working proud, gracious actions speaking aloud
Your humour, haunting my head like a terminal tumour
Thinking unsure, you helping, what you're good for
A broken lock with a rusted key, my love you will set me free
Ageing into the night, living on like a thousand year old light.
