Mental health is this:

_A man must see that his life is pain and sorrow and fear, and at the same time he must have his first glimpse that it need not remain that way._

"You must not refuse the pain of seeing that you and you alone are responsible for what happens to you inwardly. You must accept the pain of seeing that whatever happens to you in your mind and feelings and in your life, you must accept the pain of seeing that you and only you are responsible for that devastation being there and remaining there.
When you accept the pain and as you being responsible for it being there you will then see that the explanation for your wrong life and painful life, you will see that the explanation of the pain is in the pain itself." ~ VH

You know how to deal with humanity along mercantile lines. You will keep yourself healthy by declaring that: "No evil can come nigh me. God is my health” ECH
