Bab 46: Realm Racial Ranking and Potential.

The body, soul, or consciousness, and the origin core are the three centers of power in the void universe. Every organism must have at least one of them from the largest creatures to the smallest invisible creatures and it is generally accepted that the Origin core is the most powerful center of power. 

Creatures within the universe gain power by strengthening the body, followed by the soul, and finally the origin core. The path of perfection embodies this endeavor and aims to achieve perfection through the fusion of the three centers of power into a single entity. 

Creatures with only a body can only achieve the mana body state of evolution. Those with a body and soul can reach the level of transcendent on the path of perfection. It is only those with an origin that can become origin gods and achieve true immortality.
