Mechanics of reincarnation on earth?

[likeitblue]

Reincarnation as a concept never puzzled me until I read Ra materials. From Buddhism to Seth books I took it for granted that one could reincarnate to any race/gender anywhere on earth as suited for/warranted by one's development need and karma. With its elaboration on the 75000 year cycle and how entities incarnate to earth from different origins (some from Maldek, some from Mars, some native grown on earth and some from different far away planets or galaxies!), reading Ra has been an eye-opening experience for me.

This thing about entity's varied origins and Mar's entities' altered genetics by Yahweh etc. made me wonder about the mechanics of reincarnation on earth. Are Maldek's and Mar's entities sharing their genes with other 'starseeds' and native earthlings in a big melting gene pot? or do entities reincarnate according to their origin's gene pool? Maldek reincarnate only as Maldek and Martian's 'special' genes remain only available to original Martian entities? Such divisions would seem not consistent with LOO, but if all entities of different origins will share a common gene pool once we started the cycle on earth, why was Yahweh's error in altering genes of Mars' entities significant? Also, Maldek seems to have a special karma alleviation thing that's borne only by Maldek entities, I don't see them sharing a big reincarnational pool with other non-Maldek entities. Anyways, am i to infer that reincarnation is done within the boundaries of the entities' origin? which doesn't seem right though.

Maybe I am thinking about this all wrong, and would love to hear what others thought about the mechanics of reincarnation based on Ra's info.
