Reincarnation - The mystery of Mithra

An important mystery of the universe and the nature of human existence was written and given to 12 people named the sons of Mithra to teach others. But because man was imprisoned in the body, could not understand words and thought that language was the mystery code. So the name of this science was changed to the mystery of Mithra. Over the years, parts of these knowledge have been used in alchemy and sinister purposes. So the generations of 12 people decided to hide these knowledge. After centuries, the sentences of these secrets heard from a person. But words were still difficult for humans to understand. So explained by example. But it was still not understood. And after him, this secret disappeared again and to this day, everyone is looking for that secret.
