...and then the garments ruled by themselves. During that time, they cannot be considered the feet of Atzilut, and instead of being the feet as they had been, they were left as worlds on their own.
Part 2: This is called a fall for them... Although the orderly array of the worlds (in their rectified state) entails that Beriyah, Yetzirah and Asiyah should initially be garments of Atzilut and afterwards worlds in themselves, the process we are discussing was not like this. Rather, it is called a fall – i.e. the death of the kings....for they had fallen from having been included in Atzilut as its garments and were now ruling by themselves... The order in which they spread forth (after the Tikkun) is that Atzilut remains, while it is the garments that extend in the sense that control is given to each one of them to draw its share from Atzilut, as stated above. Here, however, Atzilut is concealed, and the garments do not channel its influence in an orderly way. Rather, it is a fall for them because it was not that they spread forth but rather that Atzilut departed. After having previously been the feet and garments of Atzilut, they were then left as the worlds of Beriyah, Yetzirah and Asiyah on their own, since they lacked the body which they had been clothing.
