All the sannyāsīs are assisted by brahmacārīs, who are described as follows: One who knows his real identity and is fixed in his particular occupational duty, who is always happy in spiritual understanding, is called Svarūpa-brahmacārī. One who completely knows the Brahman effulgence and is always engaged in the practice of yoga is called Prakāśa-brahmacārī. One who has acquired absolute knowledge and who always meditates on the Absolute Truth, knowledge, the unlimited and the Brahman effulgence, thus keeping himself in transcendental bliss, is called Ānanda-brahmacārī. One who is able to distinguish between matter and spirit, who is never disturbed by material transformations, and who meditates on the unlimited, inexhaustible, auspicious Brahman effulgence is a first-class, learned brahmacārī and is named Caitanya.
When Sārvabhauma Bhaṭṭācārya was talking with Gopīnātha Ācārya about Śrī Caitanya Mahāprabhu’s sannyāsa community, he appreciated the first name, “Śrī Kṛṣṇa,” but did not like the surname, “Caitanya,” which is the name for a brahmacārī belonging to the Bhāratī community. He therefore suggested that the Lord be elevated to the Sarasvatī community. However, Gopīnātha Ācārya pointed out that the Lord does not depend on any external formality. Gopīnātha Ācārya was firmly convinced that Śrī Caitanya Mahāprabhu was Kṛṣṇa Himself and therefore independent of any external ritual or formality. If one wants to engage in pure devotional service, he does not require titular superiority as a Bhāratī or a Sarasvatī.
