As spirits we have always existed in a generalized form, since we are all part of the universe. As individual spirits, we have existed for a timeless time.
This is just one little lifetime in a succession of lifetimes.
Reincarnation is not something that occurs at death; it is something that takes place at every moment. Death and rebirth are occurring every second.
We're not really indigenous to this world, this world being a temporal plane of reality.
Reincarnation is a process in which a finite being will go through a series of transmutations and will perceive different things. There will be a continuity of perception.
Reincarnation is happening all the time. Every moment we are going through a change. Our being isn't solid. Reincarnation is now.
It is really hard to talk about reincarnation because you have always been and you will always be. You just experience different things in different ways.
The inner aspects of reincarnation have to do with where you put your mind. The more expansive state of mind you enter into, the less suffering there is.
