Root is my physicality bound with that of the Earth – a relationship enabled by gravity. What weakens the root, and eventually eradicates it altogether, is the mind's conviction that it doesn't need the Earth, the mind's assumption of immortality. My physical body is perishable – this is my only certainty, my mortality – and the weight of death – immanent or impending – is what makes my root strong, because gravity just isn't enough on its own. The root isn't only a physical earthing, it is a sobering of the mind, a control of the spirit.
