Sil Krandiea Kariagi Cosami prys ofte mny epeil beiances una Sir Krena Caitanya and Lord Nityānanda, who are like the sun and moon. They have arisen simultaneously on the horizon of Gauda to dissipate the darkness of ignorance and thus wonderfully bestow benediction upon all." Together, Lord Caitanya and Lord Nityānanda inaugurated the saṅkīrtana movement in Navadvīpa, chanting Hare Kṛṣṇa and dancing through the streets with their thousands of followers.
Later, Lord Śrī Caitanya sent Nityānanda Prabhu from Jagannātha Purī back to Bengal, or Gauda- desa, and Lord Nityānanda Prabhu overflooded that country with the transcendental loving service of the Lord. Śrī Nityānanda Prabhu is by nature very much inspired in rendering transcendental loving service to Lord Kṛṣṇa. Now, being ordered by Śrī Caitanya Mahāprabhu, He distributed this loving service anywhere and everywhere. Caitanya Mahāprabhu used to address Nityānanda Prabhu as His elder brother, whereas Nityānanda Prabhu addressed Śrī Caitanya Mahāprabhu as His Lord. Although Nityānanda Prabhu is none other than Balarāma Himself, he nonetheless always thinks of Himself as the eternal servant of Lord Śrī Caitanya Mahāprabhu.
Nityānanda Prabhu requested everyone to serve Śrī Caitanya Mahāprabhu, chant His glories, and utter His name. Nityānanda Prabhu claimed that person to be His life and soul who rendered devotional service unto Śrī Caitanya Mahāprabhu.
