Answer: It is because the wisdom of Kabbalah is beyond the Machsom (Barrier), beyond the border to the spiritual world. If you transcend the Machsom, you can come near this wisdom and use it, but only to the extent that you acquire a Masach (Screen). But you don’t need a Masach in order to use all the external sciences. So why isn’t it forbidden to use all the external sciences the way it is forbidden to use the wisdom of Kabbalah?
Our sages restricted themselves and prohibited the dissemination of the wisdom among the people. Why wasn’t there such a natural restriction to begin with? Why can’t a person use the forces of nature according to his spiritual and mental development? If there were such a prohibition, we could never reach the recognition of evil, which is the purpose of the existence of our world. We have to allow the ego certain freedom so that people who are immersed in it will discover the evil in their existence and wish to ascend above it.
If the ego were limited, a person would have no choice and could not reach the recognition of evil. There would be nothing we could do in such a world. Imagine that we couldn’t do anything bad; in that case, it would be impossible to reach the recognition of evil. We would live like animals; like all the other levels of nature.
A person in our world is different from all the rest of nature because he uses his evil force in order to reach scientific achievements. The force of evil is in his heart, which means in his egoism, and by developing science he uses it for the sake of his ego because the desire to receive comes before the mind and controls the mind. This is the reason that if a person has an evil will; his mind becomes evil as well and he thinks about how he can use science for his own personal benefit, as if for his own sake, but in fact it is in order to harm others.
The purpose of the development of external sciences is to reach the recognition of evil. This is precisely what we exist for: in order to realize that we will never reach a good life through science or by excelling in anything. This is the meaning of the recognition of evil, when we discover that every phenomenon actually harms us because we use it egoistically and cannot do so any other way.
Science has always been the pride of mankind because we have developed it by ourselves and it is the fruit of our intelligence, of our internal development, both spiritual and mental. This distinguishes man from animals. But suddenly it turns out that science actually turns us into poor miserable creatures, below the animal level. This is called the recognition of evil, an outcome we cannot believe. After all the great efforts we have made for ages in the hope of being able to control ourselves and nature, we find ourselves humiliated by the evil in us.
I feel that a donkey sits on my neck and that I carry it on top of me. This is the reason that we don’t want to develop anymore and feel disappointed. We don’t regard scientists and philosophers with the same respect we had for them in the past. There is nothing sacred and no authorities for modern man any more, and we intentionally ignore anything that belongs to the human level, even if it is musicians and writers. We don’t care about anything because we are disappointed by everything and so we don’t expect anything of our development but harm.
This is the feeling that is now spreading in humanity. No one is impressed by different academic degrees such as doctorates in science, professors, or titles like president anymore. There is no respect for any position anymore and this is actually a good thing because it is a sign that we have finally reached the right discernment and have realized that we have used all the good tools at our disposal in order to bring ourselves to the lowest possible level.
Young people today don’t want to study, to work, or to take any responsibility. Ninety-nine percent of them prefer not to get up from the sofa as long as someone turns on the TV for them and feeds them. This is a good and natural thing because this is how we reach the recognition of evil.
There are two periods in the development of science: the first period in which our sages concealed the wisdom; a period which lasted until the 16-17th centuries, until the era of enlightenment. Then the wisdom of Kabbalah came out of its hiding and after the Ari the whole world began to wake up. Time began to advance increasingly faster until we have reached the current crisis.
