And as those rivers, when they are in the sea, do not know, I am this or that river,
2. 'In the same manner, my son, all these creatures, when they have come back from the True, know not that they have come back from the True. Whatever these creatures are here, whether a lion, or a wolf, or a boar, or a worm, or a midge, or a gnat, or a musquito, that they become again and again.
