Namaste.

Druidism also has reincarnation in its belief system as well.

Ancient Druidism is a bit sketchy though as not enough information survived after the Christianisation of Ireland and Britain.

However, what little information that did survive has been incorporated into Neo-Druidism so much that Reincarnation is now a valid and quite believed concept in Druidism (I did look into it earlier on this year, so thankfully none of my info is guesswork).

With its love for nature, respect for wildlife and a pantheon of gods, I wonder if it is a distant cousin (very distant) to Hinduism (possibly due to the pre-historic Indo-European religion that spread when civilisation branched out from the Caucasus).
