Soul transmigration is the belief that a person’s soul can be reborn into another person or animal. This is different from reincarnation in that the soul does not necessarily take on a new form but rather inhabits another body.
If your soul is transmigrated, you will retain the memories of your previous life. This can be a good or bad thing, depending on how your previous life ended. For example, if you died in a car accident, you may not want to remember that.
