Akashic Record is a term from Manichaeism (also known as Mingjiao in ancient China), which refers to the image record of all events, activities, thoughts and feelings since the beginning of time. It is said to be printed on Akashic. Akasha is a kind of starlight, a liquid ether that ordinary people cannot feel. It is said that only a very small number of people (such as those who can possess ghosts and gods) can see the secret records of Akasha.
