Reincarnation and the cycle of rebirth.
While ordinary people romantically discuss past lives and reincarnation, it is merely an efficient system, fully controlled. Humans possess something called a soul line, in addition to DNA, and that is what defines you
While familial connections are important, the soul line creates a much stronger bond.
And a select few individuals fully understand this mechanism.
For example, the famous general George Patton, known for his phrase "Be bold! is a reincarnation of Hannibal Barca.
Adolf Hitler is the reincarnation of King Nebuchadnezzar of Babylon, who destroyed the Solomon's Temple in 586 BCE, the reincarnation of King Herod the Great, who sought to kill young Jesus, the reincarnation of the general and later Roman Emperor Titus, who destroyed the Second Temple in 70 CE, the reincarnation of Emperor Hadrian, who expelled Jews from Judea in 135 CE, and the reincarnation of King Edward I, who expelled Jews from England in 1290.
