Baal HaSulam, “Preface to the Book of Zohar,” Item 26: Also, one does not execute anything during the building, but only according to the details arranged before him in the blueprint…. Thus, there is not a single, tiny item, generated in this world, that does not extend from Ein Sof, from the first state of the souls. And from Ein Sof, it extends to the world of Atzilut, meaning specifically associated to the thing actually being generated in this world. And from the world of Atzilut, the generation extends to the three worlds BYA, where the generation appears in actual fact, where it stops being Godliness and becomes a creature, and to Yetzira and Assiya, until it extends to the lower one in this world.
Only one thing was created: a desire. The created being exists in this desire and feels, thinks and understands in it. The greater one’s desire is, the more he can feel and understand. The more varied the desire, the more ways he can perceive reality.
If the created being’s desire had stayed the way it was created, it wouldn’t have felt anything. This is a result of the four phases of direct Light. Our development begins when the Light begins to influence the desire that was created as existence from absence. All along the way, the desire developed by the Light and received attributes, changes, and urges to act from it. In the Light there is the thought of creation, so when the desire was created by the Light, this thought was put into practice in it.
When the desire developed, it began to perceive different impressions from the Light that turned into receiving. It receives, feels, understands and responds. Every action of the Light initiated the mechanism of changes inside the desire: It absorbed it again and again, felt, and responded numerous times.
Actually the Light is fixed and doesn’t move. It only presents itself to the desire this way. It is in the desire that all the changes take place, until it “turns around” so many times and accumulates so many changes that make it stop and start its way back. The Light is in a state of absolute rest and it fulfills its inner plan, which is for the desire to return to the source, but so that it itself wants to return to the point where the Light gave birth to it, and to justify its creation. Thus it justifies and understands the Light.
All the way into our world and back again is by means of the Light. When the Light shines upon the desire and draws away from it, it spreads from the top down. Then the Light performs the opposite action and the created being begins to draw closer to it, but it does so consciously, wanting to return to the Light, meaning to resemble it. Then he receives the surrounding Light that helps him, and he constantly wants to acquire the inner Light instead, in other words, wants to become like Him.
According to my free will, the Light influences me and changes me. Then I acquire equivalence of form and the inner Light spreads inside me. This is the level of my bestowal. So from a distance, the desire to receive returns to the Light and is incorporated in it.
Thus we attain the Creator’s initial plan and then different general parts of the “blueprint.” The “blueprint” itself is in the world of Atzilut, and we are in the worlds of BYA, dealing with its fulfillment, in the correction of the matter of the desire. Like an architect, a person builds his home and acquires control over his vessel.
