On one hand there are many souls and each of them is divided into more parts. But on the other hand, can spirituality be divided into parts? We know that there is one whole reality and nothing but that. Even when we are confused as we see its separate parts, it is actually one whole since only one state was created from the beginning, one soul.
It is called the soul of Adam HaRishon (first man), Malchut of Ein Sof (Infinity). After the preparation, we discover this inner reality behind the Partzufim and the “worlds” much more clearly. It’s about a desire that is adhered to the Creator. On the root level of adhesion, it is called Malchut of Ein Sof, and on the fourth level of adhesion it is called the soul of Adam HaRishon. It’s all about how we see this desire at a certain point of our development.
So only the world of Ein Sof was created or the soul of Adam HaRishon and nothing else. This soul is in every person called “Israel,” which means Yashar—El (straight to the Creator), who has attained spirituality. What is more, it’s whole in everyone, since spirituality is not divided into sections and parts as we see in corporeality. Only the lack of correction prevents me from seeing the real picture, but I am in it nonetheless, in the initial state of one soul that was prepared for us to reveal.
But Kabbalists say that there are 600,000 souls that are divided into “sparks.” So what does this structure stand for, a “genealogical tree”? This is the distorted picture of reality that is divided by the force of the corrupt desire in each of us. First this desire separates and totally prevents the entrance of the Light, being totally opposite from it. Then, by the force of correction, the desire starts to receive the intention of in order to bestow, or in other words, it is refined. To the extent that it has this intention, the general soul illuminates in it. This means that the desire gradually discovers its real state. First it feels that it’s a small part of the general soul, and finally it discovers that it’s the same as the soul. Then it discovers that it is Adam HaRishon.
