Help us understand soul fragmentation needing an exchange of lost or extra soul fragments. In what way does such a wound harm the soul compared to ordinary karmic trauma?

This is essentially an attack on soul attributes that results in corruption or diminished effectiveness through a kind of scarring, an overlay of negativity that is a self-imposed constraint, a hindrance to, in effect, impair the self as a coping mechanism. But, in actuality, it goes against the innate makeup intended to be present for the incarnation underway. So that creates a unique set of liabilities in defining the target of the corruption, being the interdimensional DNA, so to speak, versus cells of the body, or implanting false beliefs directly to create a source of inner conflict with other beliefs held, and so on.
