906. A certain angel related to other angels in an angelic manner how many kinds of felicities there are in the interior heaven. This he did to the distinct perception of the angels by an enumeration of them and an angelic representation. To me, however, that representation was not perceptible except by means of undulations, from which it was given me to know in a general manner that only the genera of felicities of the interior heaven were enumerated. Those which were enumerated and represented to the life within the first 4 or 6 minutes were 478 in number, thus nearly 500; hence I reckon the number 500. Since the felicities of the interior heaven are of so many genera, it can thence be concluded how many are the species, there being innumerable species of each genus; and hence how many are the particulars, these being innumerable in each species; besides the many subdivisions, namely, the particulars of particulars, since each particular is taken as a species, or as a universal genus, higher or lower, according as it is within a society where such specific or particular felicity lives.
