Is it Reincarnation or is it that your Ancestors and 'Like Minded' Spirits join with you on a Journey that they began eons ago, that you as an intimate extension of themselves, are following, and that your children will eventually continue as you go into the beyond to your place in the netherworld.
Additionally this includes spirits around you who have interests and backgrounds similar to yours - and even the spirits of those whom your ancestors wronged and are seeking their revenge on you. This leads to what we call 'karma'..
And don't forget the Angels. They are all around you.
All of these invisible forces influence our daily lives for both good or ill.
