Answer: Yes, there are different periods in human evolution that are more intensive or less intensive, etc.
We live in a very special time, the cornerstone of an intense period of mankind’s development, when all his past development of systematized, stored, connected, and integrated evolution has come to one common denominator—to the conclusion that the world now needs to reverse and change from reception to bestowal. Therefore, currently we are experiencing a very serious step in the evolution of mankind!
We should be thankful to the Creator for the opportunity He has given us; as Baal HaSulam says: “I am glad that I have been born in such a generation when it is permitted to disclose the wisdom of truth.”
We are witnessing increasingly greater changes today because we are implementing what Baal HaSulam and Rabash prepared for us. We are the souls who pave the road for all the other souls to the Creator’s palace, to adhesion with the upper force, to the ascent up the 125 levels of the upper worlds! We are laying the foundations for the revelation of the Creator.
Our situation is the most critical in all of human history, because this is the first time we encounter such changes. Like a ray of light in complete darkness, distant and totally different particles that have been shattered and dispersed in the great dark space of the general soul are now gathering and beginning to reunite into one whole!
It is great joy that it all happens with us and to us, joy that we are the ones to be rewarded by it! Therefore, we must make greater efforts in order to comply the one creation and to resemble it.
