I lived my days apart,
Dreaming fair songs for God;
By the glory in my heart
Covered and crowned and shod.
Now God is in the strife,
And I must seek Him there,
Where death outnumbers life,
And fury smites the air.
I walk the secret way
With anger in my brain.
O music through my clay,
When will you sound again?
Siegfried Sassoon
