What is Reincarnation ?

Reincarnation: The CYCLIC aspect of the manifestation of consciousness (or Soul), through a temporary and impermanent vehicle (or body).

This video is a basic definition of cyclic phenomenon called reincarnation. Because the soul seeks to increase its scope of consciousness through this impermanent dimension, it must reincarnate until this growth process is complete. This takes way more than the short time a humain body or vehicle normally lives. Hence the necessity to reincarnate.
