Coldplay - everglow lyric

Oh, they say people come
They say people go
This particular diamond was extra special

And though you might be gone, and the world may not know
Still I see you celestial

Like a lion you ran, goddess you rolled
Like an eagle you circled in perfect purple

So how come things move on?
How come cars don't slow?
When it feels like the end of my world
When I should but I can't let you go

But when I'm cold, cold
When I'm cold, cold
There's a light that you give me
When I'm in shadow
There's a feeling you give me, an everglow

Like the brothers in blood, sisters who ride
Yeah we swore on that night we'd be friends till we died
But the changing of winds and the way waters flow
Life as short as the falling snow
Now I'm going to miss you, I know

But when I'm cold, cold
In water rolled, salt
I know that you're with me, and the way you will show
And you're with me wherever I go
And you give me this feeling, this everglow

Oh, what I wouldn't give for just a moment to hold
Yeah, I live for this feeling, this everglow

So if you love someone you should let them know
Oh, the light that you left me will everglow....
