Human resonance is quite the interesting topic indeed. To understand human resonance in conjunction with a practical approach to psychology, you can have quite the understanding of what messages humans will reject or take in, and how to make them do the opposite. Now i, of course, must ask for you to not misuse this technology. Do not indoctrinate, do not force people to believe lies. Someone is going to, and the media is going to blame me, but at least those who take up the initiative to read can know that i tried.

Anyway, the proper way to visualize a person in Human Resonance is a fractal wiggly line. A message is another wiggly line, like a wave that travels straight. Each line has a frequency, and humans can increase or decrease their frequency. I am sure you have heard that expression before. Anyways, a message that is actually understood goes into the human line and merges seamlessly. It may take a while for the message line to find the right space, or the message line might wait until the human increased their frequency to a specific degree before merging. This is true understanding, the message line becoming part of the human line.

We take in many messages, every single day. There are big ones, and there are small ones, but we would not be as human without every last one. This modern society makes us sink to a low frequency, one where we cannot truly understand messages, and these messages cannot merge with our human lines because we simply are not in the right space to understand them. 

Now this is why quite a lot of people are hasty to immediately dismiss spiritual and religious material, and yes, this is because of beforementioned problems with society, but also their human line rejects those message lines because of simply how low their frequency is. Quick note, apathy is the lowest form of living. What you can then do with this is understand what their human line takes in and what their human line bounces off, and with this understanding you can then bring the light of the truth to their being. For example, an argument with an apathetic materialist;

P1: “Witchcraft is a sham designed to make money!”
P2: “It is a historical fact that lines of folk practitioners exist in places like Africa and Latin America since the times when witches were, in your eyes, real”
P2: “It is also a fact that you cannot find the part of the brain that consciousness comes from, and where consciousness stops and ends. There are many phenomenons that come from consciousness that actually happen, and the amount of these things that happen are actively proving the existence of of the spirit, are they not?”
P1: “Even if that is true, people still make money from it!”
P2: “Well i should hope so! While fraudsters are enevitable, the vast majority are people who genuinely want to fund their lifestyle, community, hobby, etc. The notion that witchcraft was just made up to sell books and courses is silly, it’d be like book makers inventing Jewish people to sell bibles!”

This is a perfect example of an argument using a practical approach to psychology and human resonance principles to triumph. In their mind, science has not been set free from materialism. You reply to materialistic questions with materialistic answers, the spiritual reality of the universe is truth, and to deny it is to use logical fallacies and mental gymnastics to answer your questions, which obviously can be countered easily.
