The Lord's early life was recorded by one of His chief devotees and contemporaries, namely Śrīla Murāri Gupta, a medical practitioner of that time, and the latter part of the life of Śrī Caitanya Mahāprabhu was recorded by His private secretary Śrī Dāmodara Gosvāmī, or Śrīla Svarūpa Dāmodara, who was practically a constant companion of the Lord at Purī. These two devotees recorded practically all the incidents of the Lord's activities, and later on all the books dealing with the Lord, which are above mentioned, were composed on the basis of kaḍacās (notebooks) by Śrīla Dāmodara Gosvāmī and Murāri Gupta.
