The value of any wisdom in the world is according to the purpose that it yields. This is the goal to which all the scrutinies aim. Therefore, a wisdom without some purpose is inconceivable except for infants playing games, since to pass the time they come and this is their purpose, according to their value. For this reason, a wisdom is not evaluated by keenness and proficiency, but according to the merit of the purpose that it yields.
You therefore find that any external wisdom is only for the purpose of corporeality, which is sure to be gone today or tomorrow. In that case, it is sufficient for the subject to be as the predicate.
And although the wisdom has many advantages over these subjects, for wherever it is, it is nonetheless a spiritual element, but we have already said that it is evaluated by the purpose, which is its persistence for eternity. And if the purpose is transitory and fleeting, it is lost along with it.
(Baal HaSulam, “The Wisdom of Israel Compared to the External Wisdoms”)
Naturally, our universe and its laws, which seem to us unshakeable, has its beginning and its end. There is a beginning, middle, climax, and then decline, reduction, and extinction in the development of any dynamic system.
Therefore, today we see that the laws we study and consider to be absolute exist only in the framework of our senses and only with regard to us. If our senses were different, we could attain totally different laws and connections.
Question: Does this means that you have to change internally in order to become a physicist? I study and explore how the world around me changes and create the necessary instruments.
Answer: On the whole, when I study something in any field I can freeze a certain parameter and keep studying with a fixed parameter.
It is the same here when we are subconsciously frozen in our egoistic senses and use them to explore the world. Therefore, it seems to us that there is nothing but the world that we see, but we forget that we perceive everything through our senses that are initially fixed by nature.
If we could change them, a totally different science would emerge based on our new senses. This variable dramatically changes all the laws as they turn from absolute laws to relative laws. It turns out that on every level and in every internal change a totally different science is created, a different state, a different world. This is what a person attains.
According to the wisdom of Kabbalah, when a person begins to change 125 fixed types of changes appear in him and accordingly 125 worlds, 125 levels or depths of attainment, which means 125 types of science.
But when you attain the uppermost level all your previous attainments merge into one single whole that is called the world of Ein Sof (Infinity). We cannot understand that yet, because we probably undergo a special transition there. This transition is still unattainable for us.
