Time period of Osho's original talks/writings

Ten years have passed since, in the words of his attending physician, Osho prepared for his departure from the body that had served him for 59 years "as calmly as though he were packing for a weekend in the country." This volume is a recognition that the time has come to provide a historical and biographical context for understanding Osho and his work. Who was this man, known as the sex guru, the "self-appointed Bhagwan" (Rajneesh), the Rolls Royce Guru, the Rich Man’s Guru and simply the Master?Drawn from nearly 5000 hours of Osho’s recorded talks, we hear the story of his youth and education, his life as a professor of philosophy and years of travel teaching the importance of meditation, and the true legacy he sought to leave behind: a religiousness religion centered on the act of meditation and the teaching of "Zorba the Buddha", a celebration of the whole human being.
