Thank you @irime! I cannot say for sure which follows which. Re-ordering our mental and emotional space vs our personal exterior spaces. It seems to be, if you start with one the other will follow.
I believe this is why monks and nuns of what ever religious persuasion keep their spaces assiduously clean and tidy, it helps with the inner peace and builds a discipline of the heart and mind.
That is not meaning to say, eliminate all chaos from our lives. We do need a little of that, as it is what makes us alive... especially if one is an artist. ;-)
