When our human vessel is feeling depleted and in need of a recharge, we can make a direct connection to this solar stream of energy and light and plug ourselves in to this source stream.  This is what happens here at Inner Space, and what I designed the octagonal rainbow grid to help us do.  Anchor in and conduct the Rainbow Rays of Solar Light and Source Codes into the cells of your body, into your energy field and your light body matrix.
 
How do we “plug in”?  There are many ways, the most direct, easy and powerful way I have found is to go outside, and stand in the sunlight.  And breathe it in, and drink it into your pores, and make a conscious connection to the sun itself.  Make each breath fueled with your intention to pull in sunlight to your body, to your cells.
 
This sunlight comes encoded with the Rainbow Rays.  Just like a prism diffracts the sunlight into the rainbow spectrum, your crystalline energy field does that same thing.  You can think of your chakras as doorways or receiver sites for the solar rainbow energy. 
Red Ray enters your field through the doorway of the Earth Chakra (tailbone)
Orange Ray flows through the Water Chakra (sacral)
Yellow Ray blazes through the Fire Chakra (Navel and Solar Plexus)
Green Ray breathes into the Air Chakra (Heart and Lungs)
Blue Ray enters the portal of the Ether Chakra (ears, mouth, throat)
Indigo Ray is transmitted to the Light Chakra (3rd Eye, Pineal Gland)
Violet Ray enters the Crown (source spirit portal, fontanel)
 
And the Rainbow Rays merge into the oneness of the White (Soul Star Chakra, 8-12” above the head)
 
I’ve included some pictures of myself doing this (anchoring in and plugging into the Solar Rays). 
 
This Sound Tuning also opens you and assists to receive the solar rainbow codes, through the musical scale.

Your core is a filament for energy flow.  It is a column of light.  This column can be as thin as a gossamer strand, or as wide and magnificent as you create it and empower it to be.
 
The ancient yogis called this strand of light the sushumna nadi (sushumna = she who is most gracious, nadi = stream or flowline).  This central nadi is the main flow line for the energy field of your body.  It is the major central river of life of the human body.
 
This central channel works a lot like the wire filament of an incandescent light bulb.  The more prana/energy/electricity you pour through this filament, the brighter your light shines.
 
The doorway to your core is your belly, your navel and solar plexus.  Bring your attention into this core door (your upper abdomen) and access this central light channel.  Do this by feeling your skin and surface of your belly (with a helpful notice of your breath moving the belly, or the feeling of your clothing on the skin there).  Then take your attention into the depths of your belly, deep deep into the core location of the spine.  Once you “hit” the central channel you will feel a “zip” line of energy awareness from tailbone to top of skull.
 
Run your breath and your attention down to the tip of your tailbone as you breathe out, and up to the crown of your head as you breathe in.  Get your life force flowing in your central channel.  Turn on your inner light bulb!
 
Connect again to your core, your soul center. 
Then make a connection from your personal human body core to the core of the earth body.  Run your energy down through the soles of your feet, through your energy roots, deep into the soil of the earth, through groundwater pockets and bedrock, through layer after layer until you feel warmth.  This warmth leads you to the molten core of the earth.  Breathe in this liquid fire light, and offer your inner sunlight and warmth back to the earth in a feedback loop, belly to earth core.  Once you get that running, make an intention to connect with both the solid iron inner core of the earth (for strength and stability, for magnetic spin).  Then make an intention to connect to the crystalline core of the earth (a geometric lattice work of crystalline light).

Keep running this loop of your body core to earth core with every breath.  Keeping that connection, extend your awareness up up up to the sun.  It can help to reach your arms overhead and/or cast your gaze upwards.  With open arms, call in the light and warmth and full spectrum light from the sun.  Pull it with each inhale into your belly, and with each exhale extend your inner light up to greet the incoming sunlight. 

Visualize and feel a huge column of light, from earth core, through and surrounding your body and up on into the sky and extending up to the sun. Step your feet a bit wider apart and open your arms a bit wider than shoulder width.  Visualize this as a magnificent column of light, with swirling energy flowing up and down and all around in flow.

Though these instructions are detailed and your first few times of doing this may take a bit of time to focus on, once you get the hang of this it can be done in a quick instant at any time anywhere with your attention to connect to core, earth core, solar core and invoke your light column.  A quick easy fun way to raise your vibration and increase your light quotient!
