When you look for "why", you're not always looking for the answer to why. You're just trying to reflect on what you think. Trying to compare with outside view.
There are objects you're attempting to control or change, and the purpose for that. You're invested in it. There are many objects, they're all mediums for you to experience & look within, or to look at yourself and focus on what you are...beyond the simple labels. More like, what you contain in terms of undiscovered mind. Rules of design.
