HaVaYaH (Yod-Key-Vav-Key) is the only model the Creator imprinted on the desire created by Him “from absence.” The whole creation is included in these four phases that continuously expand and unfold in the worlds.
Yet, we never leave Malchut of the world of Infinity that begins to develop within itself, and that’s what we regard as the worlds of Adam Kadmon and Atzilut, the breaking, the worlds of Beria, Yetzira, Assiya, this world, and us in this world. All of this remains inside that very same Malchut of Infinity.
All these worlds appear in relation to those who are attaining Malchut’s properties and the place where they reside. Thus, Malchut reveals itself to them. And this is why we say that we are in “this world.” But what is “this world”? It is the same Malchut of Infinity which is, however, so dark, so self-restricted that we experience it as “this world” instead of the world of infinite Light.
When we begin working and drawing the Light there, aligning ourselves with the Light, we will begin experiencing, instead of this world, the worlds of Assiya, Yetzira, Beria, and so on in a greater degree, until the entire Malchut gets revealed to us in full.
After it was created, this Malchut was in its primordial state (1); now we are in it in the process of correction (2); and in the end, we will come to the state of the final correction (3). Yet, it is still the same creation, one Malchut of the world of Infinity.
