807. The very fact that it absolutely cannot be sensed and that it stands out as a "blind spot" is so to speak one of the strongest proofs of its elevated existence as the eternal "something" in every living being that rules over the senses and thereby over life itself. If it were not sensed as a "blind spot" there would be no differentiation between what can be sensed and what cannot be sensed, that is to say, between the "created" and the "creator". If the "creator" could also be fully sensed, it would be "matter", it would consist solely of combinations of movements and there would no differentiation between "I" and "it". But if this were so, everything we know as a state of contrast would not exist either, for the differentiation between "I" and "it" or between the "creator" and the "created" is the deepest or absolutely primary cause of all contrasts. There are no contrasts that are not based on "I" and "it". As an example, let us imagine the two contrasts: "black" and "white". What is "black" and what is "white"? Is not each of these expressions a description of its own particular form of "it"? That we express one of them as "black" and the other as "white" is just a way of indicating two specific relationships that this "it" can have towards the I. But if the I did not exist, a specific relationship could not exist between this "it" and the "I", and consequently no contrasts either. Exactly the same applies to absolutely any sort of contrast that we might point to. Each one of them without exception exists only as a specific relationship between "I" and "it".
