You are what you look like.
What you do is reflected unto your physical form.
It is a looping feedback.
A criminal will look like one, a hero will look like one, a villain will look like one.
To change is easy if you can change how you appear but to make sure that the cup is clean one must always clean it inside before cleaning the outside.
There will be fools who imitate actions but have opposite intentions - beware of them and beware of it yourself.
But in the end - to know the self matters not. To make the self ideal - better - but to make everything better or to keep peace free is the highest action.
