In other words, the overall Malchut is a bond of all the individual Malchuyot of each of the ten Sefirot. Even so, these separate powers would be hanging in suspense but for one general, overall law which they need: namely that the lower realms should exist. This general law or power (the overall Malchut) includes all of these specific powers (the individual Malchuyot of each of the ten Sefirot). This is what makes the potential actual. The bond of all these powers contained in each of the individual Sefirot to bring forth the lower realms is the law called Malchut.
