I think you will find it interesting that the realizations and transformations are not a straight line or series of steps toward spiritual enlightenment. Rather they outline a path of necessary experience that winds deeply into the ego self of the material world and back in order to arrive at an experience of enlightenment. Progress does not always mean that you are moving in the direction of being more spiritual. That's not always the direction of the path. Sometimes being less spiritual is the direction of progress.
Religions tend to form around the spiritual high points of the path.
And until a person falls into sin and is excommunicated, there is no further progress. The last step before sainthood is to commit an unpardonable sin. It creates compassion and empathy for the sins of you fellows. Not doing good would seem very odd to someone who alsyas did good. Word lessons can be presented as a straight path to enlightenment, but not world lessons.
