All realms are mental realms, therefore, reincarnation or rebirth happens within Mind. Whatever one is thinking within the moment of the thought-feeling, is the thought that Mind is wearing within that imaging-emotion.

One moment, Mind might wear the thought "I am a beast!" and for that moment, Mind is bestial, an animal is imaged and the emotion of self-loathing arises. The next moment, Mind might wear the thought "I am divine!", and an image-emotion of Jesus and forgiveness arises. It is the imaging/emoting that keeps Mind within the wheel of rebirthing and reincarnating. So, believing in reincarnation, thinking about reincarnation, is to be caught in the thought of reincarnation, which is to be in the moment-by-moment reincarnation of these images of what reincarnation is or is not.

When all imaging ceases, reincarnation ceases.
