Buddhaghosa was a 5th-century Indian Theravada Buddhist commentator, translator and philosopher. He worked in the Great Monastery Mahāvihāra) at Anurādhapura, Sri Lanka of the Vibhajjavāda school and in the lineage of the Sinhalese Mahāvihāra.
His best-known work is the Visuddhimagga (“Path of Purification”), a comprehensive summary of older Sinhala commentaries on Theravada teachings and practices. According to Sarah Shaw, in Theravada this systematic work is “the principal text on the subject of meditation.” -from Wikipedia
At the Ranch, in Rajneeshpuram, I worked in the Buddhaghosa department. Which is the name that Osho gave to the department that was responsible for the sale and distribution of all of Osho’s books. Part of that work included the warehousing of all of Osho’s books. We had three co-ordinators, Ma Prem Gatha, Ma Prem Gyano and Swami Rama. They were a triumvirate of coordination.
Some of the sannyasins who worked there were, Ma Yoga Rabya, Swami Red Hawk, Shailandra and Amit (Osho’s brothers), Swami Keerti, Ma Dharma Jyoti, Ma Prem Kaveesha and these are just a few, there were many others.
So where is everybody these days: Gatha lives full time at the Ramana Ashram in Tiruvanamalai, India. Gyano lives and works at the Insight Mediation Society in Barre, Massachusetts. Swami Rama worked closely with the American Advaita teacher Robert Adams in Sedona, Arizona, before Robert’s passing, and has himself passed on a few years ago. Ma Yoga Rabiya lives at a retirement home in Ashland, Oregon, she must be in her 90’s and is still going strong. Red Hawk is a renown poet and author of eight books. Shailandra is leading meditation meetings. Amit is living and working at Osho International Meditation Resort in Pune. Swami Keerti started OshoWorld, is the author of numerous books, and leads meditation camps around the world. Jyoti lives and works at OshoDham in Delhi and also leads meditation workshops. Kaveesha started the Osho Academy in Sedona, and passed away in 1999. And myself, I am maintaining the blogsite Sat Sangha Salon at o-meditation.com which posts the words of many buddhas, mostly from Buddha Osho.
