In some myths, Raven stole the sun (the ultimate shiny!) to bring it to man. When I realized that this was why Raven was my primary spirit guide (because I also want to bring warmth and sustenance to people), it suddenly made sense. (It wasn't that I rejected Raven; I was just kind of curious as to why the connection seemed so strong and important.)

So, keeping in mind that this is why I choose the word, the word I'd use to describe you is "warm".

Because there is sunlight within you (well, the local equivalent) that is good, warm, light that nurtures and strengthens.

(Hey, you said "one word" you didn't say I couldn't explain! :-) )
