But this is not all. This paragraph of the Prajñāpanā goes on to tell us that these sammūrcchima humans are microscopic in size, and their life span is only momentary, less than 48 minutes (antar-muhūrta). Although they have five senses, in terms of consciousness they are insensible. They are truly unusual human beings, stranger than anything found in the Book of Dzyan.
When I summed up the teachings of the Book of Dzyan on the four modes of birth in a single paragraph at the beginning of my first post on this topic, I necessarily made broad generalizations. Human evolution covered an immense period of time, and there were obviously many gradations in the general modes of birth given for the different humanities. The third humanity, for example, can be divided into three main stages. The first stage of the third humanity was still sweat-born, like the second humanity. The second stage was the egg-born. We are told that the separation of the sexes occurred in the fifth sub-race of this root-race (SD 2.715 fn.). So the womb-born was the third stage of this humanity. Likewise, we may assume that the sweat-born went through many gradations and stages. One stanza refers to this mode of birth as “budding,” much like the udbhijja or sprouting mode of birth taught in Hinduism for plants. Whether the examples given for the sammūrcchima humans in the Prajñāpanā have any relation to the sweat-born can only be known when the secret commentaries on the Book of Dzyan become available, or perhaps if the lost Jaina Pūrvas and Dṛṣṭivāda become available. The strange sammūrcchima humans born by agglutination in human excretions certainly present us with an enigma.
