Since that time, the cloak and the method of receiving knowledge through the heart, symbolizing the highest level of divine illumination, and conferring honor, recognition and respect on the recipient, has been handed down through an unbroken succession of Sufi masters. This significant act creates the only hierarchy within the School of Islamic Sufism. The designated Sufi Master, called the Pir, is the essence of the Sufi Way. The present Pir, Molana Salaheddin Ali Nader Shah Angha, was officially appointed as the forty-second Sufi Master in the unbroken chain of transmission on September 4, 1970, when the cloak of Muhammad was bestowed upon him by his father. The son, grandson, and great-grandson of previous Pirs, Pir's spiritual training naturally began at birth. The Pir has written more than fifty works in prose and poetry. He continues his great-grandfather's tradition of presenting the ancient truth of Sufism into scientific language.
The Oveyssi School began as a force in the US in 1979, when the Pir, Molana al-Moazam Shah Maghsoud Sadegh Angha and his son and successor, Salaheddin Ali Nader Angha, moved from Sufi-Abad, outside Tehran, Iran, to California. At first, small sessions were held in private homes. In 1981, Molana Shah Maghsoud Sadegh Angha passed on, and Salaheddin Ali Nader Angha, designated in writing and at a public ceremony on September 4, 1970 as the next Pir, became head of the School. Pir Nader Angha had attended high school, college and graduate school in the U.S., studying mathematics and physics. He has continued the work, begun by his great-grandfather, of translating the traditional terminology of Sufism into the language of science. Under his leadership the school has grown rapidly, and he now supervises more than 500,000 students worldwide. Maktab Tarighat Oveyssi Shahmaghsoudi (M.T.O. Shahmaghsoudi) is incorporated in the U.S. and Europe as a non-profit educational and religious organization. Each year new centers are opened all around the world. Maktab Tarighat Oveyssi Shahmaghsoudi (M.T.O. Shahmaghsoudi) Centers now exist in more than 20 countries. In the USA, 16 states have a center and most major U.S. cities, including New York, Chicago, Miami, Orlando, Tampa, St. Louis, Sacramento, Denver, Salt Lake City, Columbus, Albuquerque, Plainsboro, San Diego, Atlanta, Virginia Beach, Portland, Seattle, Dallas, Houston, San Antonio, Phoenix, and Washington, D.C., plus 9 centers in the San Francisco Bay area and 8 centers in Los Angeles and suburbs. The newest and largest Sufi Centers are located in Falls Church, Virginia and Frisco, Texas. The Falls Church center, outside Washington, DC., seats 1,100 people under the central dome. Designed by the Pir, the magnificent design is based on the traditional science of letters and numbers (Jafr), representing metaphysical truths in physical form. The beautiful Memorial Building for Molana Shah Maghsoud Sadegh Angha, constructed in 1982 in Novato, California, whose design is also based on the science of letters and numbers, is a gem of Sufi architecture, incorporating many traditional arts and crafts rarely seen. It is visited by thousands annually.
Many Maktab Tarighat Oveyssi Shahmaghsoudi (M.T.O. Shahmaghsoudi) students are of Persian descent, but students come also from diverse religious, ethnic, geographical and cultural backgrounds, and the proportion of non-Persian students is steadily increasing. In fact, Sufism fills a spiritual need , most dramatically epitomized in the popularity of Rumi’s poetry. Students, particularly new students, tend to be young and well-educated. The vast majority of students have or are attaining college degrees, and a substantial number have graduate degrees as well.
Students wear white to symbolize the state they wish to attain --- purity. Following the Quranic injunction:
Conversion to Islam is neither suggested nor required. On special occasions, special services are held. During the Gulf War, a special peace service was held near Edwards Air Force Base in California and beamed by satellite to Europe. Five thousand people attended. An extraordinary invitational session marked the Opening of the Washington Khaneghah.
Independent research within different fields is conducted under the supervision of Pir Nader Angha. Examples of current topics are: "Sufi Practices and the Rate of DNA Repair and Psychological and Physiological Effects of Fasting." These two examples illustrate the focus on melding of the mystical and the scientific.
Programmes for children and youngsters include Persian teaching and Tamarkoz Meditation, summer recreational retreats, and their own annual Celebrations.
Speakers from Maktab Tarighat Oveyssi Shahmaghsoudi (M.T.O. Shahmaghsoudi) frequently present lectures on Sufism and on Islam to public schools, community colleges and universities.
