Good morning, Asha.
Thanks for your encouraging comments regarding my article. I enjoyed your poem, as well. I particularly liked the first five lines of your final stanza, as it reflects on emotions that I have experienced (an, dare I say it, everyone will recognize). As you work on revision, let us read it again!
I have read about mind-mapping, and do believe it works much like clustering. The version I read about included little drawings, which frightened me away because even my stick figures need help!
I keep turning back to clustering - it seems to work well with the way that I think and helps me get to my emotions. I can see that mind-mapping would also be very helpful. Any technique that can help us break through our "internal editor" can be useful to writing from our hearts.
