From an article by Rabash: “The old’s contradiction—a construction, youth’s construction—a contradiction.” “The old” are those who are used to God’s work, “Youth” are those who are just starting their work. A contradiction is a descent or a fall, which means that first there was an ascent in the work that is considered a construction, which means that they considered the ascents, but the contradiction is when they felt a fall, which comes from the concealment of the Creator, which means that the Creator conceals Himself from them, and this is called a contradiction. The old’s contradiction is when they say that the Creator sent them the concealment, so it turns out that they are already in construction, since they believe that the Creator is taking care of them and from this they receive livelihood.
“The old” are those who are already accustomed to the spiritual work, and so they know how to interpret every state, how to approach it and how to make it beneficial. So even their “contradiction” is construction. This is because they don’t forget and hold on to the intention that everything comes from the Creator, even the descent. So it is during the descents, by remaining loyal, by holding on to their faith, to the intention of in order to bestow even during the descents, that by that they construct the ascents. The descent itself turns into an ascent.
The ascent does not come after the descent, but it is the same decent if a person attributes it to the Creator, to the goal of creation, and understands that he feels it in desires to receive and adds the right intention to it: The descent itself becomes an ascent.
A person immediately rises by the descent that is felt in the egoistic desire, by the revelation of the corrupt vessel. Then he stops moving up and down on a wave of ascents and descents. He is always happy about the descents, because it isn’t after they are over, but while still in them, that he adheres to the Creator. So the contradiction that old men feel goes to their construction, since from it they build an even more intense adhesion with the Creator.
The “youth” are those who have no power yet, not enough support from the environment that could stabilize them that enables the turning of the descent into ascent, into adhesion. So they even begin to use their ascents egoistically and enjoy the good feeling, thus forgetting the intention. Then the ascent turns into a descent, and the construction turns into destruction. The state is determined by a person’s intention.
