We "descended" from the World of Infinity to this world, from the property of bestowal to the property of reception. As we descend, the property of bestowal within us is decreasing, and, accordingly, the fulfillment (the Light, the sensation of the Creator) within us is diminishing as well. This continues until we reach the state of "our world," where all traces of the Light and the spiritual vessel (the desire to bestow) disappear totally, and we find ourselves completely cut off from spirituality.
Above our world, in the worlds of Beria, Yetzira, and Assiya, there exist the broken souls, that is, the souls that sense their egoism. We need to "enter" there from our world, meaning to reveal that our souls are broken and disconnected. Afterward, we have to pass the border that separates the Worlds of BYA from the World of Atzilut (Parsa), that is, to fulfill the requirement of joining the process of correction: to wish to attain love and complete unification.
By doing so we awaken our broken souls so that they include themselves into Malchut of the World of Atzilut which initially is merely a point that exists on Hazeh (chest) of Zeir Anpin. Above Zeir Anpin, there is GAR of the World of Azilut: Atik, Arich Anpin, Aba ve Ima, and Yeshsut. Above it, we find the next border: Tabur of Galgalta, the World of Adam Kadmon, and the World of Infinity.
In our world, our souls are points. This is how a person perceives his spiritual state called "this world." Later, by attracting upon himself the Light that develops him, a person attains the sensation of himself in the worlds of BYA, that is, the sensation of the broken, egoistic desires (the states of the Egyptian exile).
From there, we need to ascend toward the Light, meaning above Parsa because it’s impossible to perform the correction in the worlds of BYA, where there is no Light of correction but rather, the Light that exposes the evil. The Worlds of BYA (a place, a state, a sensation) are intended for the realization of evil, of the broken souls, so that we reveal how bad we are and how strong the grip of the evil inclination is. Then, to the measure of this revelation, we will be able to ascend upward and connect to Malchut of the World of Atzilut.
The inclusion into Malchut of the World of Atzilut is called raising MAN, our prayer. Malchut of the World of Atzilut passes our prayer to Zeir Anpin of the World of Atzilut, and, as a result, ZON raises the MAN to Bina of the World of Atzilut. Then the Light (the Reflected Light or the Light of AB-SAG) comes from Above, corrects the connection in ZON, and fills them (ZON).
That is, we only need to raise Malchut of the World of Atzilut, Shechina, that is now in exile. Everything that exists in the Worlds of BYA are parts of this Malchut, Shechina. We need to raise our desires there. Malchut of the World of Atzilut is the "Assembly of the souls of Israel" (Israel is those who aspire "straight to the Creator"), that is, the connection of the broken desires.
Inasmuch as we are able to connect, we include ourselves into Malchut of the World of Atzilut. Surely, we cannot accomplish it ourselves; we can only ask.
Malchut passes our request about uniting to Zeir Anpin, and to this very measure reveals that she wants to connect with Him. Meanwhile, ZA has to receive the desire to connect with Malchut from Bina. And then both, ZA and Malchut (ZON) rise, each with its own desire, to Ima (Bina), which unites them.
Afterward, ZA descends to its place, gives birth to Malchut, and connects her to itself. To the extent that ZON are connected, the souls that exist in them participate in this connection and get filled from it. That is because these souls comprise the body of Malchut.
