At the same time Rick and Maria posted a similiar discussion on their own blog, which you can see here http://zentangle.blogspot.com/2010/11/conversation.html . I just have to say the email sent by that person was in turns hurtful, insulting and annoying. I wonder why people take the time...if you don't like tangling, ignore it, no one is forcing a Micron pen and lovely Italian paper into your hand.
For some reason I had never thought to look up the actual definition of the word doodle. Here is what I found on three different web dictionaries.
A doodle is a type of sketch, an unfocused drawing made while a person's attention is otherwise occupied.
make a doodle; draw aimlessly
doodle - scribble: an aimless drawing
Zentangle is the opposite of every red word you see above. It is focused, purposeful, and intentional drawing. As you create, it will draw you in and center you. It's breaking patterns down and reinventing them. It is relaxing and fun.
What I gained from all of the comments and discussions is a greater understanding and even more enthusiasm for this art. The bottom line for me is Zentangle is a philosophy, a method of drawing patterns that can be taught in many variations. I can also say with certainty that had I sent a question out to the universe about the process of doodling, I would never have been wrapped in the supportive arms of community or encouraged with words of wisdom as I was by my fellow CZTs when I posted my Zentangle question.
I'll close with one of my favorite comments, one by Nancy Ubin: There is room for all perspectives, turn your tile. Not only important in tangling, but also in life!
