Reincarnation

Reincarnation represents the ability for a living being's soul to reconstitute itself into another form upon the death of its original form. The concept hearkens back to Hindu tradition where it is believed that the karmic value of a person's life in one world would determine his or her form in the next life. As such, animals be find themselves reincarnated into people, and people may find themselves reincarnated into animals.
