First, i use the word Negative for communication here. they are not good or bad. Believing in them usually make us feel bad, but all emotions are what they are; Emotions.

The goal is to agree to experience this as it is. There is no goal here to take out / get rid off / release / change what comes up. This clarification is important because we usually try not to experience the emotion. To agree to experience it without wanting it to disappear. 

Usually when unpleasent feelings arise, they also contain emotional baggage from the past that makes the emotion stronger than the local incident that occurred. So in addition to the ability to experience emotions in the present, it can help to do some process of cleansing and healing of past experiences. 

In addition, if our thinking patterns habitually interpret reality in a negative way or we have all kinds of limiting beliefs, it can surely be benefitial in addition to do a process of change and growth in this area.

By the way, our emotions show us a map of where we are. For example if I'm angry because I did something that I did not want to, its a mirror of something i did. I can learn from it.

Suppose you experience an unpleasant emotional state. Okay. What do you do with it? When we experience emotional pain it is immediately reflected in the body. Emotions may be experienced as a physical pressure, a sense of suffocation, pain and contraction in a particular area, sense of warmth, or anything else that is felt unpleasant.

The natural tendency of humans is to try to get rid of the bothering feeling that is being experienced. If you read the text when you are feeling emotional pain, its likely to be easier for you to see it. But even if you do not experience a dramatic emotional pain now, probably you have some sort of tiny thing bothering right now that you can work with. 

Several common methods for dealing with painful emotions are repression, making an addiction (drinks, cigarettes, sex, food), an attempt to express the emotion on another person (shouting, arguments, physical violence or verbal), a phone call to a good friend, getting inside ashield and being alone, and complaining. 

People do not experience their feelings but become these emotions. In order tosee this just recall situations where you have experienced painful feelings and remember the way you acted.

If a person was truly experience his emotionswithout turning to be them, and without justifying them, shortly after experiencing the emotions, the feeling and the negative emotion are released.

The usual situation is that emotions arise inside, as a result of our interpretation about a particular situation (ex, someone looked at usin the street, we interpreted that as something not nice, the emotion of anger appeared in our inner space, and now we're a bit angry, and then we become the emotion. 

Now we are angry for a whole day. What is the difference between feeling the emotion and becoming the emotion? Suppose an anger showed up. Now we are the anger. We are angry!!! Do not mess with us now,grrr brrrr Argh, oh oh oh someone here is angry. Usually we continue to feed our minds (With our imagination, thoughts, emotions) with the situation that occurred or with the situation we interpret we are in it, which strength the emotion or inflames it and creates emotional heaviness. 

Thinking again and again about the situation that occurred, thoughts and imaginations about it, may take the form of stuff like this - "How does he look at me?", "How dare he to do this to me?", "He went there and just smiled at me with his arrogance," "Who does he think he is", "it is wrong" and things like that. It was just an example. see it in your specific examples.

When we do experience the emotion, in this case anger, without becoming the anger, we experience the emotion in the body (ex, the physical sensations that the emotion creates) without thinking again and again about the story of the situation that occurred. We feel the physical sensation in the body, entering it by our attention, feeling the body from within. 

This is a sensory process and not a thought processing. it is based on bringing attention to the area of the body, sensing the place inside and allowing space for a physical sensation in the body itself. To understand this, try it the next time you experience unpleasant emotion. Understanding occurs through the application and practical repetition, so understanding won't remains only as a thought. 

When you accept all emotions, they are not your enemy anymore. they didn't come to upset you. they just want healing and love. 

emotion body experience doesn't suggests that we should be passive. Sometimes people who hear this for the first time, interpret it incorrectly. For example, if someone's car was taken by the city because of parking and he is very angry now. regardless of the experience of the emotion fully, he goes and takes the car from where it is.
