The sense of sight requires focusing, and the focusing faculty of a human being requires 20 vibrations of the brain. So when the baby starts reaching out for a toy, it starts developing the focusing faculty at 20. Then we get stuck at that. But when the brain was evolving, we didn't do this. Nobody taught us how to use it, so we bypassed it.
Nobody knows, really.
In my case, I think it's because my father died. I had nobody to ask questions to. That could have been why, because when I was tested at the university, I was using the frequency normally. That is correct. The right one to think and the left one to act.
