As beauty is to the eye of the beholder , so is truth to the ear of the listener. To many the length of your poem would be appropriate to honor their god. I liked the openness of the gods identity and could be related to many religions. The one thing that jarred with me was the inconsistent structure and syllable count per line as well as an irregular rhythm. I hope I'm making sense here. For instance the first stanza,:
My god is :
my morning light 4 syllables
When the day begins 5 syllables
My candlestick at night 6 syllables
When my day comes to
its end. 7 syllables
By writing the stanza again perhaps as :
My morning light
When my day begins
my candle at night
When my day does end
I don't feel the flow and rhythm in your lines . I think that a subject like the god you are describing would be better served with more rhythm and harmony in the lines lengths perhaps more detail to technicality, I am not sure as I haven't studied poetry format since high school , just what I feel when I read you work. Do like the essence though..Warm regards..Iain
