The bringing forth of the secrets of the Mysteries

In modern handbooks on Physics it is stated as an opinion—though it is really to be regarded as a definition, but it is not a matter of logic)—that the physical body is ‘impenetrable.’ A physical body should be defined as that of which it can be said, that when in one place, no other body can occupy the same place at the same time. This must be put down as a definition—instead of which we now have the dogma: the bodies of the physical world have the quality of impenetrability. Whereas it ought to be: two bodies cannot occupy the same place simultaneously. (This, however, is philosophy.) ‘Nezach’ expresses the self-manifestation of something in space to the exclusion of something else; it represents something a degree coarser than Hod. What lies between these two is the degree expressed in the word ‘Jesod.’
