This whole thing is sort of hard to explain, I will try to do so as simply as possible

Basically the whole thing begins with Lorkhan creating Mundus, in which his reasoning  was so that the original spirits could achieve CHIM. After his own attempt to achieve it he realized it was impossible for the original spirits to achieve CHIM as their level of existence was too high making it hard for them to percieve themselves and realize their own limitations. For this reason, Lorkhan began to formulate Mundus as a way to put the original spirits to an existence of severe limitation (i.e mortality) in which all would be at the apex of self awareness and would be in the position to jump past their own limitations and acheive CHIM (or more).

Here is where the Man-Mer schism comes into play. While Man, in essence, prefer the suffering of mortality to reach greatness, Mer, in essence, would rather return to their original existence in unity with their creators within the spirit plane.
