I know that the answer to the question "Which of the three people mentioned in not related to either of the other two?" is in "According to this narrative, shortly after the birth of young prince Gautama, an astrologer named Asita visited the young prince's father, Suddhodana, and prophesied that Siddhartha would either become a great king or renounce the material world to become a holy man, depending on whether he saw what life was like outside the palace walls.". Can you tell me what it is?
Asita
