The Chaitanya Charitamrita is one of the primary biographies detailing the life and teachings of Sri Chaitanya Mahaprabhu (1486–1533), a Vaisnava saint and founder of the Gaudiya Vaishnava Sampradaya. It was written by Krishna Das Kaviraja (b. 1496), primarily in the Bengali language, but also including a great number of Sanskrit verses within its devotional, poetic construction, including Siksastakam . Intertwined with the stories of Caitanya Mahaprabhu's life are philosophical conversations detailing the process of Bhakti yoga, with special attention given to congregational chanting of Krishna's names and the Hare Krishna mantra.
