Each of us is a particle, a fragment of the shattered vessel. If we could connect, we would become Malchut of the world of Infinity and we would feel ourselves as one soul filled with infinite Light.
But there was a shattering when the Light of Ein Sof entered the desire it had created and blew it up from the inside by filling it with the intensity of the Creator, of the Emanator. Thus the Creator inserted His desire to do good into the created beings.
It turns out that our small desire expanded all at once by 620 times than it was before, and with all this intensity, the desire drew the Light into it in order to receive, but it wasn’t protected by the conditions of the first restriction or by a Masach (screen).
As a result, there was an explosion and the desire was shattered into many fragments. Even before that it was made of many pieces: five types of desire , meaning the levels of the root phase, phase one, two, three and four ,which are different in quantity and in quality, although it had never previously felt that it was divided.
Every level is divided into five other parts and then into five other parts, etc., and the result is a huge number of particles. In every particle there is a desire that is different from the others both in quality and in quantity. The distance between the desires is the difference between the parts, and this is the reason that no one understands each other.
Because everyone is separated from the others, no one can feel his own reality since reality is felt in the whole vessel, or at least in the connection between two, when each one feels his reality in the other. The more parts one can connect to himself, the more strongly he can feel the reality. In order to reach this correction, we are in a state called this world, and by actions of connection, we draw back the great Light that left us, so that it will influence us and correct things.
