Is clean something mental or physical, possibly a combination of both ?

The way we see sometrhing as clean-or-not is usually the way we've been taught to see it. I think there is a physical minimum of clean recognised by all, and then a huge mental conception of clean which can vary so very much. I think it's safe to believe that what one one person sees as normally clean can appear as not-that-clean to another, and what is considered normally clean by one can seem maniac-clean to the other.

In short, I think it's a combination of both.

It is all mental. Everyone’s perception is different.

Society sets an ideal image of what is clean. If you slowly go back in time and slowly take away all the little inventions, like antibacterial soap, then you take away reasons for things to be considered “not clean.”

It is also proven that if you are too clean and your body does not come in contact with curtain bacteria and germs then your body does not lean how to fight it off and could potently make your immune system weak.

My physical condition is a 1000 times better than my mental condition. But it seem to help when I go for a run, I just tend to forget about my problems for a short while.

"The Path of Virtue," Jonathan Murro, and "Climb the Highest Mountain," Mark Prophet, are worthwhile.

clean has different meanings in different contexts. too many to list them all.

here, clean means 'with no traces of evidence left for police'

"we got away clean"-----porter from the movie Payback

clean can mean absence of physical impurity as when you mop the floor and get it clean

clean can just mean 'to finish entirely' as when you 'clean your plate'. that plate aint really clean

To me it is having a pure soul and conscience, and then that emanates to the rest of the body, mind and environment.

It is mental as it is subjective to the individuals perspective.

I think "clean" comes from within and then works it way out.

For me it is physical; removing old sweat, bacteria, and dirt from my body is a physical process.

When done, it cheers me up.
