I think it is a tool that makes use of the timeless nature of the soul. It's more than becoming uncaring, it can also be used to channel a positive or negative configuration of the self.
So I'd say the state of uncaringness could be a strong (strong as repeating) negative pattern of the soul that needs to be resolved to not repeat more across the cycles. It's like a defense mechanism that makes use of the ability of separation.
How to resolve? The repeated choice to not desire to be cut off from one's love or light self. Acceptance of one's feelings instead of rejection.
