There are those that will say that there is no god/God, and those that understand that gods are just a concept. We must all realize that concept; we are all in this together! Yes, there have been those religions and cults that believe the sun/Sol is the god that is spoken of, the father of us all. My only crit. here is that, it should be [hearted] not hearten. Oh, and the names that you give; they are not readily recognizable to the average person. [Who are they?] LoL ~ Gee.

I went and looked them up. I understand now, but not ALL know, only the ones that are practicing Hindus and from those parts of the world. Yeah, sometimes the computers think they know better than us. Have happy holidays and know peace. ~ Gee.

you have too much message. You have a very strong idea, a metaphor; the idea that we all accept the one sun and so should all accept the idea of the one god. This image is enough to expand into the meaning you wish to share. I think a poem should not preach so much as to imply poetic truth.

You have some strong lines like
Happy be the rejoicing
in the world's wide wing
(although "happy be" might be less awkward as "Happy is the rejoicing")

keep at it!
