The atomic shield is another term I would like to mention. As we already know we have many layers of spirit bodies that encase our physical form. Each layer has its purpose and when those layers become ripped or blocked they can create dis-ease in the spirit bodies creating what we know as soul sickness. When this happens it affects the energy centers that we know as our Chakra system and then affects the physical body as an illness or triggers an emotional imbalance. What the atomic shield does is protect us and sift out an overload of energy that can affect the physical and emotional levels of an individual.
So what happens when this field becomes ripped or torn? The answer is that you are more susceptible to picking up the energy or feelings of others to a point that it can be overly distracting, or even painful. It is like an Empath on overload... Some people will even begin to have the symptoms, physical illness, or even feel the pain that others are experiencing to the point of believing it is theirs.
Mikio Sankey, PH. D., L.Ac. mentions in his book Esoteric Acupuncture Vol. 1 that "The atomic shield is part of the outermost part of the Atomic Web which has a protective energy field, or energy shield, that is located between the etheric and astral bodies." In his book he mentions that, "It is built to block the memories of any astral travels that occur during deep sleep."
Sit in the energy for awhile as you bask in the healing light. When you are ready you can move your awareness back into your physical form and into your heart chakra feeling energized and full of light as you bring your awareness back into the room and where you are sitting. This is something I like to do in my twilight stages before I enter sleep. My suggestion is to find what times work best for you and enjoy!
Just a side note: Scientist have now discovered that the earth has the similar field to protect it from radiation of outer space.
