Castes and Tribes of Southern India/Sāstri
Sāstri.— In the Madras Census Report, 1901, Sāstri (one learned in the shāstras) is described as "unrecognizable. The word is used as a title by Smarta Brāhmans in the Madras Presidency, but the persons returning it came from Bombay, and were not Brāhmans." Sāstri is recorded in my notes as a title of Dēvāngas.
