44 There are fundamentally three kinds of Pralaya.  See S. D., I, 397-398.
1. Solar pralaya.     This comes at the end of one hundred years of Brahma.  It marks reabsorption into unity.  It marks end of manifestation of solar system.  Concerns the solar Logos.
2. Incidental pralaya.     This succeeds the days of Brahma.  It marks periods between manvantaras.  Temporary form ceases but duality remains.  Concerns a planetary Logos.
3. Individual pralaya.     Achieved by a man at the fifth initiation.  Marks attainment of perfection.  Concerns the monad.
There is also the pralaya in connection with human evolution which we call devachanic.  It concerns the personality.
