The first time his soul came into the world was as the Magid Mishne. Afterwards his soul was reincarnated as Rabbi Yehoshua Soriano, a very wealthy man old and charitable who would rise up early each morning to learn to learn and pray. Then after he was reincarnated as a young boy named Abraham who died at the age of 13. There is a type of reincarnation discussed in The Gateway to Reincarnation called pregnancy incarnation. A pregnancy incarnation is like receiving a guardian angel.
Normal reincarnation begins when the soul enters the body at birth.
Pregnancy incarnation occurs during a person's life. Due to a great merit, one can receive a guardian angel even from the holy forefathers Abraham, Issac and Jacob. This soul comes to the man to help him in his life. It does not suffer his pains and can leave him when it wants. The Arizal told the Meharcu , Rabbi Chaim Vital that at the age of thirteen he received a pregnancy soul incarnation of Rabbi Elazar Ben Arad, the student of Rabbi Yochanon Ben Zachai.
