Sai Baba is Satyanarayana Raju, an Indian guru who goes by the name of Bhagavan Sri Sathya Sai Baba and who says he was born in 1926. (Critics claim the birth date was fabricated to make it appear as if Sai Baba's birth fulfilled a prophecy of Sri Aurobindo. They say school records prove that Sai Baba was actually born in 1929.) Sai Baba and his followers believe he is divine. He claims to have paranormal powers and to be able to work miracles. Two of his favorite "miracles" are to make ashes materialize for poor people and to make jewelry materialize for rich people.
