Emotion

We communicate our emotion.
We started by communicating and we still are communicating physically, chemically, biologically, eventually using voice, emotionally, and mentally.
Emotional communication is communication with the outside world by triggering physiological reaction
it's limbic and automatic, we can only control it after it happens
Per-linguistically, we still communicate physically, chemically, biologically, using voice, and emotionally
Lizzard's behavior is not acceptable in society so we use words to hide it (diplomatic)

so, an effective communication is kinestetic and physical ( or chemical, biological, voice, emotional)
mental communication is abstract communication
like picture is more than a thousand words, words can't even paint a picture
picture can't ever paint moving picture
moving picture can't even paint reality

The physiological reaction could be sad, mad, fear, happy, etc that lead to cry, threat, act violent, smile, etc.

Inside our body, we still communicate physically, chemically, and biologically, even with our environment. However, in social environment, we communicate through air (voice) auditorally through voice and visually through body language or gesture (emotion).

we are emotional being, we are mentally emotional being. Without mental, we are animal. without emotion, we are robot. we sacrifice our emotion with the development of mental. If we have strong emotion with mental ability, we are like "the rise of the ape". our emotion keep us grounded and trustworthy as social members. Since we have learn to con others through words but also gesture/act, emotion work very hard to keep us honest, guilt or shame.

Our lymbic system manage our physiological reaction and can be triggered by sensory or imagination.

Do animal has a mental "world"? It probably does has a much simpler world for an animal can be conditioned to remember signals or icons. Since our emotion react to both sensory information and cognitive information, human react mostly to cognitive information or the "world". Even though we physically live on earth, we mostly live in our "world". This world is our disposition of phenomena with names. We have to make a MENTAL NOTES about our experience to experience it. The MENTAL NOTES IS what we remember. We makes MENTAL NOTES for all experience that we see, hear, touch, etc, and thinking about our past and future. Due to ignorance, just like we thought the content of the conversation is the most important, we also think that the content of the mind which is nothing but the MENTAL NOTES is real. This is what it means by WE CREATE OUR REALITY.  We create and remember only MENTAL NOTES and we react to it. In the present, direct experience doesn't go through this mental notes. Our emotion is originally created for this.

If I remember going to the store yesterday, i had to make MENTAL NOTES yesterday or told myself that i went to the store. "I, store, driving, car". I then disposed those phenomena into memory. I don't actually observed my body going to the store or driving because I live in my mind. I am still not paying attention to what my body is doing but I know that I am typing and sitting down because my MENTAL NOTES told me.

Since emotion react to imagination, our emotion spend most of their time reacting to this MENTAL NOTES.

EMOTIONAL SYSTEM CAN PROVIDE EARLY WARNING SIGNS BEFORE PHYSICAL, CHEMICAL, AND BIOLOGICAL OR EVEN VOICE COMMUNICATION. THE MENTAL SYSTEM IS NOTHING BUT DIGITAL EARLY WARNING SIGNS FOR ABOVE COMMUNICATION.

EMOTION IS A PRE MOTION, TO PREPARE ACTION, TO GET READY FOR ACTION.
