Poetic License or Self-Indulgence?

I love writing poetry. Sometimes the ideas and words form sultry webs in my mind for me to unravel and put back together again for others to understand. For me, that is the key to my poetry. My thoughts, though tangled they may be for a time, must ultimately be understood by others for it to have value and meaning.

I find, however, that some poets dwell so far within themselves that they cannot be understood by the masses. Their readers will say, "Wow, that was deep." In other words, "I have no idea what the heck you said, but I don't want to appear stupid." Poetic license or self-indulgence?
