Chakras are the energy centers (wheels of light) in the body.  These energies with the human brain computer are like the motherboard of our spirit.  In the spiritual community there is an abundance of information about the chakras there are tons of resources available.

The Light aspect:

Root Chakra is represented by element is Earth.   The aspects are rooted in safety and security, and survival.  The ruling planet is Mars (masculine which rules Aries (March 21- April 19).  Mars is the God of War. Tuesday is the day of the week for Mars.  This planet has to do with aggression, sexuality, courage, and passion.    

The Shadow Aspect:

There are shadows are self-centered, greedy, animalistic and violent with the root chakra.  The biggest shadow is fear.  When you feel like your basic needs for survival (food and shelter) are not being met then this shadow starts to grow.  Security needs to be established.    In the times we are living in, fear is constantly being pushed by the media.  One way to deal the fear to integration. Integration means intermixing your shadow and your light so to speak; to achieve wholeness. The shadow is the part of you that has been repressed. For example,  things about yourself that you have been told were bad as a child and you locked them away in your subconscious.

There is not right or wrong way to integrate your shadow. Essentially, you are bringing your darkness to the light and owning it for what it is. The main idea is that you need to be grounded and rooted in yourself and know who you are.  Some may seek out mediation, yoga, nature, EFT Tapping, reiki, inner child work, sacred dance, and journaling.   Do what works best for you, but it starts with acknowledging the emotions (energy in motion). Remember, only you can heal yourself. You know what lurks in the deep of you soul. A true healer can only show you the path but you must walk on your own.
