Basically it has been established that there are two pathways for sight to be processed in the brain and subsequently two types of acceptance and recognition in the mind.
1) The Ventral Visual-Limbic Pathway which is the neuronal firing system that underlies overt recognition i.e I see you and I am able to place the features I see as someone I know as a pure observation - a detached and unemotional viewpoint of purposeful determining.
2) The Dorsal Visual-Limbic Pathway which is the neuronal firing system that underlies covert recognition i.e. I see you and I am able to place the features as someone I know AND the familiar emotional sensations attached to seeing you are present, therefore you are definitely the person I think you are. I feel a connection to you that enables me to certify who you are and what you mean to me.
This theory came to mind as my friend was describing visually seeing energy and asking how I 'saw' energy. Whilst both of these pathways involve processing visual input I felt their different qualities help me to understand the differing qualities between 'sensing' and 'seeing' energy.
In my case it is not so much about visibly 'seeing'. I sense energy and know it is there and can also perceive how it is interacting between people or around an individual. I do not see auras for example but can sense a person's energetic field, rather like suddenly walking through mist. It is almost as if my dorsal visual limbic system alone is in operation i.e. I recognise the energy through the sensation and affective (emotional) response I have to it, rather than purely through an overt obvious visual stimulation.
Many of us who do see energy visually have to overcome their fear of 'seeing' things which bear no relation to 'real' life or to anything they have experienced before. This 'fear' is induced by a lack of previous experience which has no prior affective/emotional connection and therefore floats freely in our imaginative realms often creating havoc since our rational mind says "this cannot be happening!".
Our emotional response will interupt and interfere very quickly if we are not certain of what we are getting involved with. This is true for any experience in life. Our emotions are primed to react far more quickly, effectively and efficiently than our rational response as the limbic system is always activated prior to the prefrontal and frontal lobes of the brain wherein logic lies. The type of experiences we have stored away in our memory banks greatly affect our reactions. Many of the old stories we have been told and been unconsciously indoctrinated with about magic and mystery need to be reexamined and often laughed at in order to release our fears.
Once an emotional connection has been made through our experiences of seeing or sensing energy as a safe and usually life enhancing phenomenon then we can use it effectively and efficiently for the benefit of all. By keeping your heart and thoughts pure, you will come to find great solace in both seeing and sensing energy.
**note: if you have had a head injury, trauma or suffered from severe headaches prior to 'seeing' energies then a check up by a medical professional is advised.
Hallucinations accompanied by radical changes in personality and impaired functioning in the real world scenario is a medical condition known as Psychosis - this bears no relation to the psychic effect of seeing energy.
