Charyāpada tradition

The 8-12 century Charyapada tradition — a corpus of about 50 mystical Buddhist Tantric songs composed by 24 named Siddhas (Mahasiddhas) in Old Bengali / Apabhramsha vernacular, representing the earliest surviving literature in any eastern Indian vernacular language. The Charyapadas were composed by Pala-period Vajrayana Buddhist Siddhacharyas (including Luipa, Saraha, Kahnupa, Shabarapa, Bhusuku and others) between the 8th and 12th centuries at Nalanda, Vikramashila and Somapura mahaviharas, and across the eastern Indian region extending into Bengal, Odisha and Assam. The songs use the twilight language (sandhabhasha) code to convey Tantric spiritual experience through everyday metaphors — fishermen, boatmen, hunters, ale-brewers. The 1907 Haraprasad Shastri discovery of the Charyapada manuscript in the Royal Court Library at Nepal transformed Bengali and Assamese literary historiography. The Charyapada tradition is the common root claimed by Bengali, Assamese, Odia and Maithili literary histories.
