This situation matches very well with what the Dark Treant spoke of: the self of yesterday, the self of today, and the self of tomorrow.
These spiritual bodies represent the self of yesterday, and the resurrected ones represent the self of today; they do not conflict with each other.
However, the situation with Shadows is a bit more unique. Those who are resurrected will lose their own shadow until they destroy their Shadow, only then can they reclaim it.
Similarly, the Shadow will sense the resurrection of its original body immediately and will strive to kill its original body because if successful, it can extract all of the life essence of the original body and replace it, becoming the unique self of today—in other words, a person killed by their own Shadow will have their soul dissipated, losing the possibility of being resurrected again. Even if the True Wraith is destroyed, the one who is resurrected in the end is the True Wraith, not the original body.
