Have you ever notice when you are happy and satisfy everyone can get it only by looking at your face similarly if you are angry, sad, scar it can be readily observed by anyone. its just a basic observation and general view. And just indicate that face is index of expressions but not the index of mind in writing and reading there is a minor difference but for understanding there is hell of difference. If a person recognize that you are happy, excited, sad or angry its just matter of your expressions think for a while if you hide your expressions then what’s happens!!!!

Simply no one can come to know that you are going to kill him or you really respect him. I am in the opinion that its blessing of ALLAH ALMIGHTY that he make our mind thoughts secrete and beyond the access of any human being no one can read our mind thanks GOD!!! We social animals are so materialistic and full of complexes in nature and thinking that we hardly think good for anyone and if we have ability to read the mind just by looking at someone face I surely predict world would subject to distractions!

Never be mistaken yourself by thinking that face is index of mind you a 20years old student hides his mind thoughts from the teacher having 20 years  teaching experience, a flattering subordinate hide his hatred and abuses in mind for stiff strict boss. A criminal can hide and act very beautifully even after murder then how we imagine that face is index of our mind. Face is just index of expressions, feelings and whatever you want to disclose. But no one can know what you desire, what is your mental level, what is your thinking just by talking to you or looking at you. You know even a physiatrist only make a guess but not sure what is the main corruption in the mind of patient. It’s the quality of ALLAH ALMIGHTY who knows better the inner hearts as He is closer then your blood veins.

Face is index of mind for only for yourself. You can readily judge what is going on in your mind and are its consequences. Have you ever notice when you think bad for any one, commit bad deed or even think of anything which is ethically or morally bad you feel your self dirty when you come in front of mirror, the mirror reveals yourself the ugliest person in the world. It’s your inner who just by your face tells you that you are on the wrong way and there is need to be careful. On the other side doing good deeds have faith in ALLAH ALMIGHTY, love for Allah’s creature and always thinks good for everyone and have a nature to serve will make you the most beautiful person in the world and you feel a satisfaction and wave of happiness on your face. Its just miracle of ALLAH that He makes our inner open for us and secret for all.
In the end I must say mind is the relation and connection of ALLAH with you there is no interference of any third person just makes this relation healthy and the reason of proud rather then a cause of guilty.
