The first reason is not knowing the best solution for avoiding evil and realizing good. Not knowing that this is only accomplished by a well-organized system that cannot and must not be based on political, religious, national, and class divisions, hatred, rivalry, and struggle. Not knowing that this cannot bring good to anyone, but only suffering and evil. Not knowing that to exist truly and thus realize good means to be material, i.e. to have a healthy and strong body and that humanity is predestined to be one body that cannot be strong and healthy if there are such divisions and contradictions within it, but only if its organization of life and work is based on the union of all, on peace, order, work, equality, love, mutual cooperation and help.
However, this should also be said and known: that in the beginning of the development of a system, there is no knowledge of what is good and what is evil, and this knowledge must be gained through the experience of doing good and evil. And this occurs exactly by applying the principle of division, rivalry, hatred, and struggle. This means that that principle as well is natural, as ignorance, chaos, and evil are one of the three natural states of consciousness. Chaos and evil cannot be avoided at the beginning of materialization and evolution because there is no knowledge. And precisely because they are evil, they will, when speaking of humanity, become the whip that will drive people to further develop their consciousness, i.e. to seek solutions and principles (knowledge) on how to avoid evil and realize good. The evolution of all things and phenomena that nature consists of has no other goal or meaning but to overcome ignorance, chaos, and evil and to gain knowledge, make harmony, and realize good.
When we speak about us people in humanity as a living and developing system, our schooling about good and evil lasts a bit longer than it should, because we have been repeating the same evils for thousands of years and we have not learned any lesson from them yet. Because of ideological-political, religious, and scientific dogmas and misconceptions from which all our evils spring, and which are constantly imposed on us through education as inviolable knowledge and truth, our schooling of good and evil will not end soon. The reason is that we people are not such intelligent beings as we think we are. Even bees and ants are far ahead of us.
All of the systems of which nature consists are strong, healthy, and stable, while human societies are time and again built and destroyed because within them some as yet untried evil and some even bigger evil than the previous one is repeatedly being created and tried out.
Another important note is that the knowledge of good and evil does not always have to be gained through experience, in a slow and difficult way. There are highly conscious energies and beings in the universe which function as guardians and carriers of that knowledge and they can always give that knowledge to us. However, those higher conscious energies and beings do not have the power to impose by force that knowledge and its application, but can only send it to us through “prophets” and “revelations.” There is no guarantee that this knowledge/revelations will be honored because the true knowledge of good and evil is not some dry and dead theory written in religious books, but a living practice that often lasts very long. It can also not bring us to the desired goal – chickens are not hatched from every egg. There are rotten eggs too. Humanity on Earth, which is not the only humanity in the universe that is developing, can be such a rotten egg.
