Emotions
Emotions and thoughts are frequencies and are energy in motion. Emotions are pure energy expressed through the human consciousness. In fact, (e)motion is really 'energy in motion'. Emotion cannot be what it is without being expressed in some way, and this provides the motion even if it is directed inward. This is the reason actions always follows thoughts. Thoughts and emotions always precipitate the action that is taken.
Emotion that is not expressed becomes inert. If it is 'held' within, it strives to manifest in other ways either by physical ailments or mental anxieties. Dis-ease may come from the lack of expressing tears or anger and that can take hold in the body which may cause psychosomatic illnesses or even long lasting physical pain. Since energy of emotion is organic and liquid, and it resists being held in a fixed state for long. Emotion that is buried often 'bursts out' through anger or crying. An outburst of anger is the same as an outburst of sadness, except that the individual is reacting to the emotion with fear.
There is a great healing in crying, because the cleansing brings motion to energy that demands release from the mind's grasp. Even anger can be healing, if it is expressed without harm to Sacred Life. An outburst of anger rapidly discharges the energy trapped within, and also shows the Heart how fearing the mind can be.
We can refer to the analogy of the rapidly moving steam molecules escaping from the kettle. We have a two-part process in expressing emotions. First we have the immediate release of energy, second is the diffusion of energy from the situation. If the mind can see how it cannot control something so fluid, then it lets go, and peace is restored through balance between head and Heart. Emotion is not to be judged it is to be allowed its existence unhindered by control. If the energy of emotion cannot be released through expression, the level at which it vibrates decreases from the lack of motion.
Without further "heat" to fuel the higher excited molecular expansion the steam eventually cools down and subsides. Emotions return to a more healthy Zero Point.
Energy is not 'good' or 'bad'. Energy simply exists. You use terms like, "This place has really good energy." But what you are really saying is that the energy moving through you is vibrating at a higher frequency and it resonates with a higher nature of your experience.
Accordingly, emotions are not 'right' or 'wrong', they simply are. Your collective judgement of emotions has contributed to the diseases that are afflicting you. To be effective in understanding how energy works, you must set aside judgement and observe its behavior.
