According to Vaisnava linguists, Srila Narottama das Thakura and Srila Bhaktivinoda Thakur wrote many songs in poetic, somewhat simplified, Bengali, that conveyed many important Vaisnava attitudes. Regarding Krishnadas Kaviraja’s “Caitanya Caritamrta”, it is said that people could learn Bengali just by reading this book in the original language.
