549. As you see, dear reader, "something No. 1" is the one and only all-dominating Absolute which exists. Everything else is, and will remain an illusion. Illusions are, however, an unavoidable factor in the analysis of the living being, because without them there could not be a "living being". These are the details of life. Life is "something" consisting of illusions. As we have now seen, this "something" is the same as "something No. 2" and "something No. 3", which again, in their highest analysis, are the same as "something No. 1".
      Thus, the two principles, "X2" and "X3" of the triune principle together constitute a "principle of illusion". It is this principle that we meet in daily life in the form of anything coming under the concept of "perspective". Therefore, here in "Livets Bog" we will define this principle by the expression, the "principle of perspective". As we have seen, all sensory perception would be impossible without this principle. But as all sensory perception is impossible without it, then this principle must be the very highest analysis of sensory perception and thereby of life itself, for life and sensory perception are, of course, identical. So the "principle of perspective" constitutes the solution to the "riddle of life" itself, and with the understanding of this principle and its solution, "life's mystery" no longer exists.
      As indicated in the foregoing, the "principle of perspective" is a unit consisting of the triune principle's last two principles, "X2" and "X3". As the cosmic analysis of this unit also combines with the one called "something that is", thereby showing it to be identical with "X1", the "divine something", then there are no more details left to analyse in the area beyond the "principle of perspective". Everything now remaining to be analysed regarding this principle – "the X's" or the "divine something" – lies below the "principle of perspective", the creative faculty, and can only appear with "relative" or "created", that is to say, "temporal", details. These details will at once prove to belong to the world of forms, i.e. illusions. Later in "Livets Bog" we will meet the "principle of perspective" again, viewed from this aspect, and see it in all its majestic outer appearance and might.
