The protective sac in which human or a mammal baby grows is called “Jarayu” in Sanskrit. Humans are Jarayu-Ja or born from the sac. Seers of ancient India, divided living beings into four categories based on the enviornment in which they mature before assuming their full individuality. Reptiles and birds are Anda-Ja as they are born from an egg or Anda. Plants are seed born or Ud-Bij-ja. Bacteria and the like are Sveda-ja; they detach from the skin of the parent like sweat.
There are higher order beings in the model of a conscious cosmos. Everyone today understands the idea of Earth being a living entity. A conscious being is associated with the Earth and other luminaries per Vedic tradition. These beings have an individual personality. Siddhar Agasthiyar calls these higher order beings as Jarayu-Ja also! Vedas say that the sac (Jarayu) in such cases is of the nature of clouds. Astronomers say that the Earth and other planets developed out of a large mass of dusty cloud swirling around a nascent Sun. Every star(Sun) in the universe developed from interstellar gas clouds. Associated units of consciousness incubated and began their individual journeys in a Jarayu!
