 Even though systematic errors in the Sanskrit of Kamarupa inscriptions betray an underlying Pakrit in the pre-12th century period, scarce examples of the language exist.The "Charyapada"s, the Buddhist ballads of 8th-10th century some of whose composers were from Kamarupa and the language of which bear strong affitinities with Assamese (besides Bengali, Maithili and Oriya), are considered the first examples of Assamese literature.The spirit of the "Charyapadas" are found in later-day "Deh-Bicaror Geet" and other aphorisms; and some of the ragas found their way to the 15th-16th century "Borgeets".
