When the time has come -- when the whirling has developed pari passu with the indwelling lives and intelligences within the cosmic nebula -- then the annular form appears, a form like a ring or concentric rings, with a heart in the center, and after long aeons, the central heart becomes the sun or central body of the new solar system, and the rings the planets. These rings condense into other bodies, and these other bodies are the planets circulating around their elder brother, the sun; elder, because he was the first to condense into a sphere" (Fund 61-2).
In the first half of a manvantara (planetary as well as human) there is the descent of spirit into matter, and in the second half an ascent of spirit at the expense of matter. A manvantara or period of material manifestation is a temporary spiritual death, whereas the dawn of the succeeding pralaya is spiritual birth.
