A Love at the level of the Soul is something that sounds beautiful and it seems that few people reach it in this life, if that were the case you could die to save the life of the other person, of course that would leave you the terrible burden of carrying our death ... that remorse can be terrible, I've heard about the survivor's syndrome and it seems that it can be very hard.
On the other hand, tying the Soul to this world for revenge sounds like a horror movie :) Well, I think it is a possible option, but some would prefer not to remain condemned to wander through this world ... maybe if the danger is not over and we have to take care of the people we left behind (eliminating the threats that remain), maybe if we are very likely to remain as guardian spirits.
I guess it is.
Hahaha. Also, creating more karma!
Sounds beautiful
