yāṅhāra hṛdaye nṛtya kare nityānanda
Yadunātha Kavicandra was a great devotee. Lord Nityānanda Prabhu always danced in his heart.
In the Caitanya-bhāgavata, Madhya-khaṇḍa, chapter one, it is said that a gentleman known as Ratnagarbha Ācārya was a friend of Śrī Caitanya Mahāprabhu’s father. They had been residents of the same village. Ratnagarbha Ācārya had three sons — Kṛṣṇānanda, Jīva and Yadunātha Kavicandra.
