Infant souls deal with issues of survival; they do not yet have a basis for making sense of what is “out there”—they only know that it is “not me.”
Baby souls have a need for structure and tend to live according to beliefs based on dogma, such as religion. Baby souls, focused as they are on bringing people together under the umbrella of civilization, see others, sometimes simplistically, as being “just like me.” They can become confused and upset when those “other me’s” act differently than expected.
Young souls are success oriented and set high standards of personal achievement. Young souls are learning to impact the world, and see others as “you”s they can impact.
Mature souls are relationship fixated and tend to gravitate towards emotional drama. Mature souls, delving into their inner world and exploring relatedness, can keenly feel other people’s “stuff,” and perceive it in the same way they perceive their own. This can make for much intensity and, often, subjectivity.
Old souls seek the larger perspective of life, and have less interest in playing the material game. They tend to be more detached, and try to see themselves and others within a larger context.
