Kṛṣṇadāsa Kavirāja Gosvāmī says that he has been able to describe these four pastimes of Śrī Caitanya Mahāprabhu by the blessings of Śrīla Rūpa Gosvāmī. Kṛṣṇadāsa Kavirāja Gosvāmī was not actually a direct disciple of Śrīla Rūpa Gosvāmī, but he followed the instructions given by Śrīla Rūpa Gosvāmī in the Bhakti-rasāmṛta-sindhu. He therefore acted according to the directions of Rūpa Gosvāmī and prayed in every chapter for his mercy.
