The broken and dead Kelim [vessels] arise with the sparks for an Ibur through the Reshimot [recollections] that received their light.
For example, after the sin of Adam HaRishon, the creatures are regarded as broken and dead Kelim. That is, their Kelim are only in self-reception, separated from the Life of Lives. There is only a spark in them from the Reshimot of Ohr Hozer [Reflected Light] that remained and descended in order to sustain the Kelim so that through it, they will be able to rise for the revival of the dead.
That spark is a spark of Kedusha [holiness] and is a residue of the Ohr Hozer. We must raise it, meaning receive it in order to bestow, which is called “raising,” meaning raising MAN. By this, a Masach [screen] and Aviut [thickness] are made, on which comes the filling, when the Ohr Hozer fills the Kelim to an extent that will clothe the lights (Ohr Yashar [Direct Light]).
