This answers an apparent difficulty, because according to what we are saying there should not be any uncertainties since it contains everything.
The proposition has two parts. Part 1: The Unknown Head... Part 2: Thus although...
Part 1: The Unknown Head is a single radiation containing all these interconnections of MaH and BaN. It is a light that cannot be grasped in the same way as the other lights. And this is the answer to something that may appear problematic. For it might seem as if there was no need to say that there are uncertainties about it. Should we not have said rather that it certainly contains all the interconnections? The explanation is that we are not talking about what is intrinsic in the Head itself but rather about our ability to grasp and understand it: one who attains a perception of the radiance of this Head cannot determine how to understand this light. However, it is a radiation that is impossible to grasp or understand at all. I.e. when looking at it.
