Translation: 
If one patiently hears about the glories of Śrī Caitanya Mahāprabhu, Śrī Nityānanda Prabhu and Śrī Advaita Prabhu — and Their devotees, devotional activities, names and fame, along with the mellows of Their transcendental loving exchanges — one will learn the essence of the Absolute Truth. Therefore I have described these [in the Caitanya-caritāmṛta] with logic and discrimination.
