Manjula, The reason you never hear about any other castes in Kashmir except the Pandit (Brahmin) caste lies in history. In the 13th century due to continued Islamic onslaught and torture of the Muslim rulers of Kashmir, most of the other caste people were forcibly converted from Hinduism to Islam including many Pandits also. Only those who resisted the pressure till the limit (mostly Pandits) remained Hindu.
