Answer: The world became more egoistic and a revolution led to drastic changes technologically, culturally, and in general. The regimes in many countries changed, farmers began to move to the big cities, and the world became more concentrated and more demanding.
It was therefore possible to begin the dissemination of the wisdom of Kabbalah in a practical manner. People began to ask, “What is the meaning of life?” And not just living like a cow that grazes in the field.
They chose to connect and to join the world, culture, and technology. There were cars, airplanes, and communication between people. Humanity became totally different. The twentieth century developed us like no other century before it, and this is the reason that the wisdom of Kabbalah was revealed.
