In 1985, following the investigation of serious crimes including the 1984 Rajneeshee bioterror attack, and an assassination plot to murder US Attorney Charles H.
Turner, Rajneesh alleged that his personal secretary Ma Anand Sheela and her close supporters had been responsible.
On 10 April 1981, having discoursed daily for nearly 15 years, Rajneesh entered a three-and-a-half-year period of self-imposed public silence, and satsangs—silent sitting with music and readings from spiritual works such as Khalil Gibran's The Prophet or the Isha Upanishad—replaced discourses.
In 1981, the increased tensions around the Poona ashram, along with criticism of its activities and threatened punitive action by the Indian authorities, provided an impetus for the ashram to consider the establishment of a new commune in the United States.
After his deportation 21 countries denied him entry, and he ultimately returned to India, and a revived Pune ashram, where he died in 1990.
His ashram is today known as the Osho International Meditation Resort.
He began speaking in public at the annual Sarva Dharma Sammelan (Meeting of all faiths) held at Jabalpur, organised by the Taranpanthi Jain community into which he was born, and participated there from 1951 to 1968.
Conflicts with various Indian religious leaders aggravated the situation—by 1980 the ashram had become so controversial that Indira Gandhi, despite a previous association between Rajneesh and the Indian Congress Party dating back to the sixties, was unwilling to intercede for it after her return to power.
