Reincarnation, original Vedic view; I don't think it necessarily included transmigration in the sense that it's understood today.
It seems to me it lacks the value judgment of modern interpretations of karmic effect on rebirth.
Everything with a beginning (Brahma) exists for a while (Vishnu) and ends (Siva), then returns in a different form, and the cycle repeats.
When I die, if I'm interred then worms convert matter to energy, and the soil is enriched -- well, in a Green burial, at least. If my ashes are scattered in water, what were once my molecules feed the fish. Maybe some fisherman eats that fish. What were once my molecules have fed things, in turn fed on by other things. Just keeps on changin' form forever, unless and until there's a final end to everything.
This applies to stars, too.
I'm sticking this here while I figure out if it means anything, for me.
