Baal HaSulam, “600,000 Souls”: It is said that there are 600,000 souls, and each soul divides into several sparks. We must understand how it is possible for the spiritual to divide, since initially, only one soul was created, the soul of Adam HaRishon.
In my opinion, there is indeed only one soul in the world, as it is written (Genesis, 2:7), “and breathed into his nostrils the breath of life.” The same soul exists in all the children of Israel, complete in each and every one, as in Adam HaRishon, since the spiritual is indivisible and cannot be cut—which is rather a trait of corporeal things.
Yet, saying that there are 600,000 souls and sparks of souls appears as though it is divided by the force of the body of each person. In other words, first, the body divides and completely denies him of the radiance of the soul, and by the force of the Torah and the Mitzva, the body is cleansed, and to the extent of its cleansing, the common soul shines upon him.
There is only one desire in reality. The Light has created a desire, and it operates on it. It restricts it, puts Masachim (screens) on it, and makes Partzufim and worlds of it. However, the desire remains the same desire. The word “worlds” (“Olamot” stems from the word “concealment” in Hebrew), and refers to the concealment of the Light in our perception and feelings. It is just like looking at the world without glasses and seeing a blurry world. The spiritual worlds are increasingly more accurate and clearer pictures that are revealed by “spiritual glasses” that I change each time as I correct myself, until I reach the world of Ein Sof (Infinity), which means the whole correction.
So, it is all about an individual perception and not about an external reality that actually exists. The picture of the world depends on the person who attains it.
On the whole, there is one soul, but each one perceives it according to his level of preparation. We are always in the same place, in the same system, but each one is connected to it emotionally and mentally to a different extent, according to his attainment and his understanding. It is like a newborn baby who hardly perceives anything. It is only after a couple of months that he begins to perceive some details of the whole picture. It is as if he is also in a state of concealment in some part and in a state of in revelation in another, and at first the concealment is much greater than the revelation.
A person gradually perceives more clearly where he is according to his advancement and his development. We are not talking about anything new, but about the revelation that is part of our perception. So, all our development is in order to awaken, to build, and to prepare such a vessel of perception that will be sensitive to the revelation of the eternal unchanging eternal reality.
Our basic assumption is that there is only one soul in the world, a desire of Malchut of Ein Sof, and we attain this state to a certain extent as if looking at it through different types of glasses that determine the level of our closeness to it.
