My dear brother, just try and examine this. Within the three worlds there is no one like Lord Caitanya or Lord Nityananda. Their merciful qualities are so great that upon hearing Them even birds and beasts cry and stones melt. ( From the Song Parama Karuna, 3rd Paragraph)

Srila Lochana Dasa Thakur expounds the most magnanimous nature and infinite mercy of Sri Caitaya Mahaprabhu and Sri Nityananda Prabhu.
