...in which the yes and the no appear at one and the same moment... These are the opposites: the one contradicts the other.
...yet we cannot even grasp how the yes and the no can both apply. It is not that we are able to understand that both of these two opposites are contained in it, for that could not yet be considered an uncertainty. Rather, the uncertainty lies in the fact that first we see it in one way but then afterwards it seems as if it was not that way at all. Accordingly –
It is simply impossible to attain any certainty about it, because sometimes it appears as if it contains the yes and then immediately afterwards it looks as if that is not the case at all. The essence of the matter is that all the interconnections stand concealed within the interior of this Head. However the Head radiates through the mystery of its rulership, and this is essentially what determines the direction of the governmental order. For the power which the Head exercises depends on the way it shines. The radiant splendor (זוהר, zohar) which shines forth from the light contained within the interior of the Head that is not Known is what rules at any given time. However, we are unable to grasp the nature of this radiant splendor, let alone the interior light itself. The reason why we cannot understand the nature of this radiant splendor and from where it derives is that one moment it seems one way and then it seems different and it is therefore impossible to understand. We thus conclude that what is within is not even seen, while even that which can be perceived – i.e. the radiant splendor – is also a matter of uncertainty and is not known. This is why it is called the Unknown Head.
