In the space between moments
In my opinion, poetry has several purposes. First and formost, to portray a vast array of feelings an emotions, to get others to look into themselves, to feel compassion, to touch their souls.
Secondly, poetry is a way to express one's own self. I, like sunshine, haven't much talent in other artistic areas, so words are the way I express myself.
Thirdly, I do believe that poetry is written for ourselves. This I know holds true for me. I know the only way for me to be truly happy is to do something for myself, and writing is that thing. If forced to write for others, for trivial things, poetry could very well lack the emotion and greatness that it has if written for one's self.
In short, I think that poetry is how we express our feelings, convey our deepest thoughts, it's therapy, it's something we do because we love it and because we need it.
