It is associated with the colour red.
The base chakra is your energetic connection to the physical world, when it is open and working properly then you feel grounded.
It is associated with physical survival, the most basic form of physical existence, the pure unthinking animal form of life, your fight or flight response.
An imbalance in the base chakra, can mean that you don’t feel connect with the real world, you feel like you are away with the fairies, you can feel physcially weak and lack self confidence.
Wearing the colour red, carrying an obsidian crystal, and using the esstential oil frankincense can help to balance the base chakra.
