The lamp lighter

Is there only, left just shards    
headaches come like thunder cracks
dark passages that are always blocked by bars  
but stars of hope, I see their glow refract
 
Thro' the fog when life brings grief
those lumens bright: a carbon arc
spotlight, the glow of self-belief
shadows flee, your glimmer flash and dart  
   
Light the lamp within my soul  
as dawn breaks on sleepy eyes  
speed the heart and take control  
release the spirit, stir its spark to fly  
   
Light the tread on each dark path  
torch I hold within, burns brighter    
it is my shield and my ever-trusty staff  
for each must be their own lamp-lighter
