This is the default level of total ignorance at which 90% of the population operates. They have no clue about anything that matters such as how fiat currency systems operate, natural cures for cancer, the true dangers of vaccines, how television manipulates their behavior and so on. (These people are often experts in sports and TV sitcoms, however.)
This level is achieved when a person realizes something along the lines of "Hey, I'm living in a dream world. I'm being told lies at every turn. What is real? How can I know what is real?" This is where people start asking questions.
A level 2 person is someone who has taught themselves a significant amount of real history and the way the world really works. This person will have knowledge of politics, psychology, world history, economics, natural health, the natural world (water, ecosystems, soils, etc.), basic anatomy, basic science and so on. Not even 1% of the population today qualifies as level 2. Most people operate in a state of wild ignorance of the world around them.
A level 3 person not only understands a great deal about the real world around them, they have also grasped ways to navigate through that world with great accomplishment and influence. They are innovators, creators and often communicators. Financial achievement is not the purpose here. Rather, it is achieving relevance in a world largely populated by utterly irrelevant people.
This level is only achieved by those of the highest dedication to spiritual awakening. You would typically only find this level of understanding in people who pursue a lifetime practice of prayer, or transcendental meditation, or a similar spiritual practice. At this level of awareness, individuals become withdrawn from the material world and really have no interest in interacting with individuals of lower levels of awareness. Far less than one in a million human beings will ever achieve level 4 "Enlightenment."
