The chakra's are the human bodys energy system. In part of when people say magick is either a hobby or a lifestyle chakra's are a large part of it. Day to day decisions you make can effect your chakra's and thus your magick can be less fluid and effective. A persons chakra's not only effect a persons ability in magick if they are closed or "gunky" for lack of a better term, your personal mindset can change as well.
The root chakra is located at the base of the spine, is red in color, its sanskrit name is Muladhara meaning root support,physical body associations are the Adrenal cortex, skeletal structure of the body, your teeth, large intestine, kidneys, and blood.
If you are fearful of something it can damage the chakra or cause it to close if open. You must realize you the fear is in your mind and not let it effect you.
An example of this happening is if someone is being made fun of or your uncomfortable around people. If you give in to the fear of the bully or just avoid people so you don't have to deal with it will cause damage to the root chakra. The root chakra is connected to the physical plane and its element is earth. If it is closed you will feel disconnected and as if you do not inhabit your body. You will feel nervous easily and unwelcome in new places.
The root chakra is about survival and making sure day to day needs are met. Making sure the body is healthy and well fed. A crucial part of opening this chakra is fulfilling the need to have somewhere to belong.
If the root chakra is closed you may feel tired and unmotivated, and you may not want to do much.
