The readers of this small description of the life and precepts of Lord Caitanya will profit much to go through the books of Śrīla Vṛndāvana dāsa Ṭhākura (Śrī Caitanya-bhāgavata) and Śrīla Kṛṣṇadāsa Kavirāja Gosvāmī (Śrī Caitanya-caritāmṛta). The early life of the Lord is most fascinatingly expressed by the author of Caitanya-bhāgavata, and as far as the teachings are concerned, they are more vividly explained in the Caitanya-caritāmṛta. Now they are available to the English-speaking public in our Teachings of Lord Caitanya.
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.
So the Lord advented Himself on the Phālgunī Pūrṇimā evening of 1407 Śakābda, and it was by the will of the Lord that there was a lunar eclipse on that evening. During the hours of eclipse it was the custom of the Hindu public to take bath in the Ganges or any other sacred river and chant the Vedic mantras for purification. When Lord Caitanya was born during the lunar eclipse, all India was roaring with the holy sound of Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare. These sixteen names of the Lord are mentioned in many Purāṇas and Upaniṣads, and they are described as the Tāraka-brahma nāma of this age. It is recommended in the śāstras that offenseless chanting of these holy names of the Lord can deliver a fallen soul from material bondage. There are innumerable names of the Lord both in India and outside, and all of them are equally good because all of them indicate the Supreme Personality of Godhead. But because these sixteen are especially recommended for this age, people should take advantage of them and follow the path of the great ācāryas who attained success by practicing the rules of the śāstras (revealed scriptures).
