CC Madhya 19.54, Translation and Purport:
"We offer our respectful obeisances unto that merciful Supreme Personality of Godhead who has converted all three worlds, which were maddened by ignorance, and saved them from their diseased condition by making them mad with the nectar from the treasure-house of love of God. Let us take full shelter of that Personality of Godhead, Śrī Kṛṣṇa Caitanya, whose activities are wonderful."
