All the chakras have positive and negative sides.
One positive aspect of the root chakra is the instinct to provide shelter, food, and comfort for our selves and our loved ones. Basically, our instinct for survival.
The shadow side of that positive aspect would be greed, hoarding, and that feeling of never having enough, of wanting it all.
It is our very foundation, and we want it to be strong and healthy. Reaching up to Balance with HEAVEN
