Exposing the famous guru Sathya Sai Baba One of the main targets during his miracle exposure campaign was Sathya Sai Baba of Puttaparthi in Andhra Pradesh state, India. Sathya Sai Baba is perhaps the most prominent god-man in India today, and was during Kovoor's time. Sai Baba claims to this day to materialize vibuthi or holy ash. Kovoor believed that the Baba performed this through sleight of hand. Many Indians throng to the ashrams of holy men who claim to perform such miracles. To expose Sai Baba and others, Dr Kovoor would produce holy ash seemingly from nowhere and distributed it amongst the audience. He would then demonstrate to his audience the sleight of hand, explaining that after some practice, anybody could perform the feat . Kovoor wrote repeatedly to Sai Baba, requesting a meeting to discuss the baba's miraculous powers. Upon receiving no response, Kovoor communicated his intention to come to one of Sathya Sai Baba's ashrams, at Whitefield near Bangalore. When Kovoor arrived, Sathya Sai Baba had gone to his other ashram at Puttaparthi. He was an efficient hypnotherapist and applied psychologist .The famous Malayalam movie "Punarjanmam" and Tamil movie "Maru piravi" was made on basis of his case dairy. From Wikipedia
