Answer: Thirst for knowledge pushed aside striving to attain the upper world and people began to engage in comprehending the material world. Since the middle of the 17th century there was interest in science and art and then the technological revolution occurred. This eclipsed humanity’s striving for spiritual knowledge.
If a person has interesting possibilities of revealing the secrets of nature of this world and attaining them, then why engage in something intangible, incomprehensible? This is how the first layer of the desire for knowledge appeared.
But at the beginning of the 20th century it became clear that science had exhausted itself and by the end of the century many scientists already said that the age of science was coming to an end and there was nowhere else to develop it. And today everyone agrees with this.
That is, there is nothing in the world we could discover that would really be a special breakthrough. There are even theorems about the finiteness of knowledge.
The science of Kabbalah explains that gaining knowledge is a human method and proceeds from our capabilities. We do not explore what the world is. We explore the world as it appears in our senses.
The world is matter given to us in our sensations. So we need to introduce a clear framework: where is the boundary of our attainment? And it turns out that it is very clear, simple, and close. In principle, we already feel it.
In this way, science, which blazed for 150 years, has practically burned out. And therefore, we are now on the threshold of breaking into the spiritual world.
Kabbalah predicted this many thousands of years ago. It clearly saw that at the end of the year 2000, when the realization of all of the ten Sefirot of the third world was completed, a feeling of their end would begin to appear as well as understanding that there should be a breakthrough to the upper area.
