The Zohar, Chapter “Pekudei (Accounts),” Item 763: The ark of the covenant in the seventh palace receives everything from the righteous, Yesod de ZA de Atzilut. Afterwards the souls come out from the ark of the covenant and enter the righteous below, in the first palace, Yesod. Subsequently, they come out from the righteous below and clothe in people. After their demise, they enter the ark of the covenant in the seventh palace so all the souls will be included from above, from Bina, the seventh palace, and from below, from the Yesod of the palaces, to be complete on all sides.
We must try to ascribe forms of unity, types of the connection between us to each word, action, and concept that we read about in The Book of Zohar. After all, there is nothing except that. It’s all about the extent and form of the connection between parts of the single soul, which for now The Zohar designates with all kinds of names, actions, and types of the relationship between us.
But essentially, all of this is designed to direct us to the only state where there are no parts, but only one desire in the unified Light. Thus we need to imagine everything that we read about in The Zohar as one system.
