  • Learning to Serve and to Roam You Could Ask Almost Any Tibetan
    CHAPTER FIVE LEARNING TO SERVE AND TO ROAM You could ask almost any Tibetan secondary student in Tibet or the diaspora where the writing system for Tibetan came from and they would tell you the story of King Songtsen Gampo and his seven ministers. While it is unclear if this story recounts actual events, it is the most well known account regarding the origins of the Tibetan writing system and as such is part of Tibetans’ collective memory. Through its retelling to successive generations of Tibetan children, it has helped to shape ideologies of lit- eracy by linking the writing system to Tibetan religion and the Tibetan nation-state. In this version of the origination story, King Songtsen Gampo, the sixth century ruler of Tibet, is credited with having sent seven government min- isters to India with the mission of bringing back a writing system that could be used to translate Buddhist texts into Tibetan. These ministers, however, met with many hardships while in India. Six of the ministers succumbed to illness or disease, leaving Thonmi Sambhota the sole minis- ter to return to Tibet with the writing system they had developed from the Indian Devanagari script. So famous is the story of this perilous journey and successful return that a statue of Thonmi Sambhota today stands in the main courtyard at the Tibetan Academy of Social Sciences in Lhasa. Outside the Library of Tibetan Works and Archives in McLeod Ganj, there is a mural depicting him sitting cross-legged writing the Tibetan alphasyllabary1 on parchment. The story of the Tibetan script, King Songtsen Gampo, and Thonmi Sambhota, however, is more than just a tale of adventure and adversity.

The digit image is divided into 64 zones. For each zone, pixel density is computed. The KNN and SVM classifiers are employed to classify the Kannada and Telugu handwritten digits independently and achieved average recognition accuracy of 95.50%, 96.22% and 99.83%, 99.80% respectively.

  • 16-Sanskrit-In-JAPAN.Pdf
    A rich literary treasure of Sanskrit literature consisting of dharanis, tantras, sutras and other texts has been kept in Japan for nearly 1400 years. Entry of Sanskrit Buddhist scriptures into Japan was their identification with the central axis of human advance. Buddhism opened up unfathomed spheres of thought as soon as it reached Japan officially in AD 552. Prince Shotoku Taishi himself wrote commentaries and lectured on Saddharmapundarika-sutra, Srimala- devi-simhanada-sutra and Vimala-kirt-nirdesa-sutra. They can be heard in the daily recitation of the Japanese up to the day. Palmleaf manuscripts kept at different temples since olden times comprise of texts which carry immeasurable importance from the viewpoint of Sanskrit philology although some of them are incomplete Sanskrit manuscripts crossed the boundaries of India along with the expansion of Buddhist philosophy, art and thought and reached Japan via Central Asia and China. Thousands of Sanskrit texts were translated into Khotanese, Tokharian, Uigur and Sogdian in Central Asia, on their way to China. With destruction of monastic libraries, most of the Sanskrit literature perished leaving behind a large number of fragments which are discovered by the great explorers who went from Germany, Russia, British India, Sweden and Japan. These excavations have uncovered vast quantities of manuscripts in Sanskrit. Only those manuscripts and texts have survived which were taken to Nepal and Tibet or other parts of Asia. Their translations into Tibetan, Chinese and Mongolian fill the gap, but partly. A number of ancient Sanskrit manuscripts are strewn in the monasteries nestling among high mountains and waterless deserts.
