Osho also known as Acharya Rajneesh from the 1960s onwards, as Bhagwan Shree Rajneesh during the 1970s and 1980s and as Osho from 1989, was an Indian mystic, guru, and spiritual teacher who garnered an international following. A professor of philosophy, he travelled throughout India in the 1960s as a public speaker. His outspoken criticism of socialism, Mahatma Gandhi and institutionalised religions made him controversial. He also advocated a more open attitude towards sexuality: a stance that earned him the sobriquet "sex guru" in the Indian and later international press. In 1970, Osho settled for a while in Bombay. He began initiating disciples (known as neo-sannyasins) and took on the role of a spiritual teacher.
