In the book known as Adhyātma-rāmāyaṇa, there are statements in Chapters Twelve to Fifteen about the worship of the Deities Śrī Rāmacandra and Sītā. There it is stated that during Lord Rāmacandra’s time there was a brāhmaṇa who took a vow to fast until he saw Lord Rāmacandra. Sometimes, due to business, Lord Rāmacandra was absent from His capital for a full week and could not be seen by citizens during that time. Because of his vow, the brāhmaṇa could not take even a drop of water during that week. Later, after eight or nine days, when the brāhmaṇa could see Lord Rāmacandra personally, he would break his fast. Upon observing the brāhmaṇa’s rigid vow, Lord Śrī Rāmacandra ordered His younger brother Lakṣmaṇa to deliver a pair of Sītā-Rāma Deities to the brāhmaṇa. The brāhmaṇa received the Deities from Śrī Lakṣmaṇajī and worshiped Them faithfully as long as he lived. At the time of his death, he delivered the Deities to Śrī Hanumānjī, who, for many years, hung Them around his neck and served Them with all devotion. After many years, when Hanumānjī departed on the hill known as Gandha-mādana, he delivered the Deities to Bhīmasena, one of the Pāṇḍavas, and Bhīmasena brought Them to his palace, where he kept Them very carefully. The last king of the Pāṇḍavas, Kṣemakānta, worshiped the Deities in that palace. Later, the same Deities were kept in the custody of the kings of Orissa known as Gajapatis. One of the ācāryas, known as Narahari Tīrtha, who was in the disciplic succession of Madhvācārya, received these Deities from the King of Orissa.
