Ś rī Harihara Bhaṭṭācārya was a professor residing in Agradvīpa. He had accepted initiation into vaiṣṇava - dharma, and was engaged in the worship of Bhagavān Śrī Kṛṣṇa in his home. But a doubt arose in his mind about Vaiṣṇavism which he could not dispel even after speaking to many people about it. In fact, such talk only agitated his mind further. One day, Harihara went to the village of Arkaṭilā, and enquired from Śrī Caturbhuja Nyāyaratna, “Bhaṭṭācārya Mahāśaya, can you tell me how long ago vaiṣṇava-dharma appeared?” For nearly twenty years Nyāyaratna Mahāśaya had laboriously studied the nyāya-śāstra. Consequently, he had become quite indifferent to religion, and did not like to be bothered with religious discussions. He only displayed any devotional tendency when he was performing śakti-pūjā (worshiping Goddess Durgā).
