CC Madhya 19.121
nijānurūpe prabhur eka-rūpe
tatāna rūpe sva-vilāsa-rūpe
priya-svarūpe — unto the person whose dear friend was Śrīla Svarūpa Dāmodara Gosvāmī; dayita-svarūpe — who was very dear to Him (Śrī Caitanya Mahāprabhu); prema-svarūpe — unto the replica of His personal ecstatic love; sahaja-abhirūpe — who was naturally very beautiful; nija-anurūpe — who exactly followed the principles of Śrī Caitanya Mahāprabhu; prabhuḥ — Śrī Caitanya Mahāprabhu; eka-rūpe — to the one; tatāna — explained; rūpe — unto Rūpa Gosvāmī; sva-vilāsa-rūpe — who describes the pastimes of Lord Kṛṣṇa.
“Indeed, Śrīla Rūpa Gosvāmī, whose dear friend was Svarūpa Dāmodara, was the exact replica of Śrī Caitanya Mahāprabhu, and he was very, very dear to the Lord. Being the embodiment of Śrī Caitanya Mahāprabhu’s ecstatic love, Rūpa Gosvāmī was naturally very beautiful. He very carefully followed the principles enunciated by the Lord, and he was a competent person to explain properly the pastimes of Lord Kṛṣṇa. Śrī Caitanya Mahāprabhu expanded His mercy to Śrīla Rūpa Gosvāmī just so he could render service by writing transcendental literatures.”
