How the Four Worlds Sorted Good From Evil

Creation did not begin sorted. The Kabbalists were clear on this: the four worlds that constitute the structure of all existence, from the highest realm of pure divine emanation down to the material world human beings walk through, were originally mixed. Good and evil were present in each world together, tangled at every level of reality, not yet separated into the arrangement where the higher worlds tend toward purity and the lower worlds tend toward mixture and struggle. The separation was not a given. It was a process. And according to Rabbi Moshe Cordovero of sixteenth-century Safed, it is a process that is still ongoing.

Cordovero's Kalach Pitchei Chokhmah, "138 Openings of Wisdom," written in Safed c. 1560 CE, describes this in terms of the four worlds: Atzilut (Emanation), closest to the divine source; Beriyah (Creation); Yetzirah (Formation); and Asiyah (Action), the world of material existence. In the beginning, each world contained both light and what the Kabbalistic tradition calls the klipot, the shells or husks that block divine light from reaching what is within them. The highest world and the lowest world alike carried this mixture.

How the Sorting Begins at the Top

The sorting process began in Atzilut. What happened at the highest level of creation, according to this Kabbalistic account of the four worlds, was a purification: the divine light flowing through Atzilut proved strong enough to push the klipot outward and downward, to the boundary where Atzilut ends and Beriyah begins. Atzilut became, over time, wholly light. The shells were expelled from it, forced into the realm below, where they mixed with the Beriyah world in turn.

Then the same process repeated. The light of Beriyah, once Atzilut had expelled its darkness into it, gradually sorted itself, pushing the klipot further down, into Yetzirah. And Yetzirah in turn pushed them down into Asiyah. The Kabbalistic tradition describes this as a cascade of purification, each world becoming more refined as it expels into the world below what it cannot hold without corruption. The higher you go in the structure of the worlds, the less admixture of evil remains. The lower you go, the more concentrated the mixture becomes.

Why the Material World Carries the Greatest Mixture

This cosmological sorting explains something that experience confirms: the material world, Asiyah, the world of physical existence, is the world where the distinction between good and evil is least obvious, where the klipot are most concentrated, and where the divine light is most obscured. Not because God abandoned the material world or regards it as unimportant. Because the sorting has concentrated in this world the shells that the higher worlds expelled. Asiyah received the overflow from above. It carries the greatest burden of the work that remains.

The Zohar, compiled c. 1280 CE in Castile, Spain, had already described the material world as the realm of divine concealment, where God's presence is least visible and where the yetzer hara, the evil inclination, operates with the most force. Cordovero placed this observation within the four-worlds framework and gave it a historical logic: the material world is not inherently more corrupt than the higher worlds. It inherited the corruption that the higher worlds progressively expelled. It is the bottom of the sorting funnel.

What Human Beings Do in the Sorting Process

The implication for human life is precise. Human beings live at the bottom of the funnel, in the world that carries the greatest concentration of klipot. This is not punishment. It is an assignment. The sorting that the higher worlds accomplished automatically through the force of the divine light pressing through them must be accomplished in Asiyah by human choice. No higher world can push the remaining klipot further down, because there is no world below Asiyah to push them into. The shells must be sorted here, from within this world, by human beings who encounter them in the texture of daily life and choose, in each encounter, to elevate the spark of divine light the shell is covering rather than feeding the shell itself.

Cordovero's student Rabbi Isaac Luria, who arrived in Safed the year Cordovero died, developed the practical implications of this framework into the detailed system of tikkun, repair, that Lurianic Kabbalah became known for. Every act of Torah study, every prayer, every act of justice performed in the material world is a movement in the cosmic sorting process, one more separation of light from shell, one more fragment of the original divine purpose reclaimed from the mixture it had been buried in since the worlds began their long descent from the source.

The higher worlds sorted themselves clean. This world is waiting on us to finish the work.
