Activation of the Chakras and Forming the Auric Shield

We were created as Energetic Beings, existing and operating of and within an Etheric Field, which is part of the Spirit. As biological creatures, our physical bodies utilize systems with specific functions.  All of these systems work together in harmony to keep our physical bodies strong and healthy.  As Souls, it's only reasonable to understand that our astral bodies thrive in the same manner, with a systematic order... the "vital organs" being our chakras, or energy centers.  In biology we learn that all organisms are responsible for maintaining homeostasis, the natural tendency of alive systems to adapt to change and remain consistent in function.  The energy body of the human does this just as much, if not more, than the physical body.  Each energy vortex (chakra) is responsible for certain functions of our being, just like the heart, lungs, and brain of the body.  Because the Spirit shapes and controls the material body, these energy centers affect the physical as well.

To better understand the function of the energy body anatomically, let us first observe a brief analysis of each energy center.

1. The "Root" chakra (red)~ located at the base of the spine, this energy center governs the feelings of personal safety and security in the area of survival.  Here is also found the basic instinct of the sex drive.
2. The "Sacra" chakra (orange)~ located a couple of inches below the belly button, this energy center governs the feelings of desire, the emotions; when we fall in love we experience a lot of sensation here.
3. The "Solar Plexus" chakra (yellow)~ although named wrongly since the true solar plexus is the heart, this energy center is located in the diaphram area, and governs the ability to use reason and logic.  Here were given confidence and solid judgement when fully opened and activated.
4. The "Heart" chakra (green)~ even though this is located across the heart area of the body, it refers to not only the human heart, but the true heart of the being's soul, and governs our true nature as divine, where we find the power of universal love.
5. The "Throat" chakra (blue)~ located at the areas of speech and sound, this energy center governs not only communication, but the beginning of awareness.  This one is much more tightly knit to the next chakra than people realize.
6. The "Third Eye" chakra (violet)~ located between the eyes slightly above brow level, this energy center governs our intuition and the connection to our higher selves.  Through this vortex comes the ability to see into higher dimensions and past the matrix of thought that we reside in.
7. The "Crown" chakra (white)~ located just behind the top of the skull, this energy center governs our connection to the Cosmic Mind and is the point of both entrance and departure of the soul to the body.

The word chakra actually originates in ancient Greek, t'akra, meaning "corners" or "edges" and was named simply because the energy centers were attached to the specific points along the astral spine, which is our antennae to earth.  This will be covered more extensively in the future.

We see here that the highest three connect us to our God Consciousness (the above) and the lowest three magnetize us to the earth (the below).  The Heart Center is our merging point where the energies from above meet with the energies from below and a cross is formed.  This cross point also acts as a stabilizer so that the awakened kundalini doesn't burn us; this keep the energies "tamed". 

When opened, either at will or subconsciously, the energy centers form layers of a protective auric shield.  You can easily activate your shield simply by imagining each layer forming as you open each energy center.  For beginners, instructions can be found here.  Now that we know the basic function of each energy center and its location, we need to see why we have the auric shield.  What exactly is the purpose of these layers? What is the aura itself?  The aura is actually the manifestation of the energy body itself, our true form as the soul.  It is comprised of seven layers, each layer corresponding to a chakra.  Each layer is also called a "body" because each one functions independently.  The physical human body vibrates at a specific rate, usually about 72 Hz.  Each layer of the auric egg, from the innermost to the outermost, increases in frequency.  We will explore more the topic of frequencies and vibration is a future writing.  The layers of the aura are as follows:

1. The "Etheric Body"~ The innermost layer of the auric field and corresponding to our 1st chakra (red), this layer is anchored to the physical body through the meridians and transmits our life force or chi.
2. The "Emotional Body"~ Corresponding to our 2nd chakra (orange), this layer actually changes color based on our feelings and can have many at one time.  This is our "mood detection" layer and the one most seen by people who have the ability to see the aura; this "body" is what they see.
3. The "Mental Body"~ Corresponding to our 3rd chakra (yellow), this layer is the part of us that is the "mind" or "ego",  and here we store knowledge.
4. The "Astral Body"~ As the bridge between the physical and the spiritual realm and corresponding to our 4th chakra (green), this is the layer that resonates with universal love, our "bare soul".
5. The "Etheric Template Body"~ Corresponding to our 5th chakra (blue), as the "control center" for communication, this body is our vehicle in the astral plane, just like our physical body is the vehicle in the 3D plane.
6. The "Celestial Body"~ As reflection of the Third Eye chakra (violet), this is our "divine self" and here we experience enlightenment and our connection to the Source, or God.
7. The "Casual or Ketheric Body"~ In correspondence with our crown chakra (white), here we reflect all of our soul memory and connection to the "universal all".  Here we vibrate at our highest frequency and we are in direct Oneness with God as a Collective.
