“O most munificent incarnation! You are Kṛṣṇa Himself appearing as Śrī Kṛṣṇa Caitanya Mahāprabhu. You have assumed the golden color of Śrīmatī Rādhārāṇī, and You are widely distributing pure love of Kṛṣṇa. We offer our respectful obeisances unto You.”
(Śrī Caitanya-caritāmṛta » Madhya-līlā 19.53 | 1975 Edition)

Śrīla Prabhupāda: “Śrī Caitanya Mahāprabhu is the mercy incarnation of the Supreme Personality of Godhead. He is addressed by Śrīla Rūpa Gosvāmī as mahā-vadānyāvatāra, or the most magnanimous incarnation. Śrīla Rūpa Gosvāmī also says, karuṇayāvatīrṇaḥ kalau: it is only by His mercy that He has descended in this Age of Kali.[…]”
(Śrī Caitanya-caritāmṛta » Ādi-līlā 7.150 » Purport | 1973 Edition)

“May the Supreme Personality of Godhead in the form of Lord Śrī Caitanya bestow His causeless mercy upon us. His smiling glance at once drives away all the bereavements of the world, and His very words enliven the auspicious creepers of devotion by expanding their leaves. Taking shelter of His lotus feet invokes transcendental love of God at once.”
(Śrī Caitanya-caritāmṛta » Ādi-līlā 3.63 | 1974 Edition & Dvitīya Śrī Caitanyāṣṭaka 8, from the Stava-mālā of Śrīla Rūpa Gosvāmī)
