For if we were to try to follow a single thing that exists below in Atzilut and trace its root in this Head, we would not be able to find our arms and legs – we would be unable to determine anything about it. We might have thought that since this Head is the root of Atzilut, we should have been able to ascend from the branch (=Atzilut) to the root (=the Unknown Head) and thereby grasp it. However, because our perception of the root is uncertain, we are unable to grasp it.
If we try to trace anything to the root, we are always left uncertain as to whether it lies on one side or another – i.e. in one given interconnection or another. This is impossible to determine, because it looks as if both combinations rule, yet this is certainly not the case. For everything surely has its own particular place – the entire governmental order runs through one particular aspect at any given time.
It is the place in the source, the ruling combination in which any given aspect of Atzilut is rooted, that is uncertain – because it looks as if it could be all of them. At first it looks like one thing, but on further examination it looks like something else, and it is impossible to come to a definite conclusion.
