Unclean folks are the people who are mentally unclean.
They think garbage and rubbish.
Leading from heaven to earth there is no dearth of such nonsensical personalities.
It is truly a surprise that such folks do live on earth.
It’s quite easy to find them out.
And primary examples among them are liars, mischief mongerers and sheer bad folks who like to do nothing but cause harm.
Well they themselves are going deep in a trap.
Simply it’s a matter of time before they are punished or made to suffer.
