23: The rising and setting of the Sun symbolises manifestation and obscuration.—S. D., II, 72.  Pralaya is of different kinds:—
1. Cosmic pralaya....The obscuration of the three suns, or of three solar systems.
2. Solar pralaya....The obscuration of a system at the end of one hundred years of Brahma.  Period between solar systems.
3. Incidental pralaya....The obscuration of a scheme.  Period between manvantaras.
Man repeats this at seventh, fifth initiations and at each rebirth in three worlds.
The Pleiades are the centre around which our solar system revolves.—S. D., II, 251, 581, 582.
The Sun is the kernel and matrix of all in the solar system.—S. D., I, 309, 310, 590, 591.
Kernel comes from the same word as corn.
Compare the words in Bible:—
"Except a corn of wheat fall into the ground and die it abideth alone, but if it die it bringeth forth much fruit."
The Sun is governed by the same laws as all other atoms.—S. D., I, 168, 667.
