That's probably the problem of civilization in general. Did people live better before they were civilized? As you know, the inner part of the brain was originally very active. In the course of civilization, only the cerebral cortex was used intensively. The exterior has thus evolved unilaterally, while the interior has remained underemployed. Such a disturbance of balance can only cause neurasthenia, nervousness and frustration - both for the individual and for the whole humanity.
I visited the frescoes of Lascaux and Tassili. Thousands of years ago, people left their pictures on the rocks in these caves. These are powerful works of art nourished by cosmic consciousness. Which painter could create the equivalent today? I cannot express a general opinion on the form in which human development has taken place, nor can I decide which would be the best. Intelligence has developed strongly since the Renaissance and cultures have become intellectualized. But what happened to wisdom? I can assure you the following: By practicing zazen, our brain can regain its normal and original state and return to the cosmic order. New energy penetrates into people, a strong activity develops, pure creative power reveals itself in them, and the ability to concentrate intuitively becomes a matter of course.
I don't know. If one asks someone: "Are you a good person?" and he answers with yes, then it is very likely that he is not as good as he pretends to be, otherwise his answer would have turned out to be more modest, for example: "Not so much", or "I don't know anything about it".
One must not want the satori and not search for it. Anyone who asks such a question will certainly want to preserve satori. Dogen in particular emphasizes that satori already exists in us, in fact even before our birth. So if we already have satori, why try to get it?
But when our life is full of passions and desires, when it is complicated, we must practice zazen to return to the normal. Zazen itself is satori. The return to the normal state is achieved through good posture, correct breathing and silence. Asking the question whether I have satori means that one has not understood what true Zen is. The right answer can only be: "No, I don't have satori, but I practice zazen, because zazen itself is already satori."
