The conversation turned to the caste-system. Sri Ramakrishna said: "The caste-system can be removed by one means only, and that is the love of God. Lovers of God do not belong to any caste. The mind, body, and soul of a man become purified through divine love. Chaitanya and Nityananda scattered the name of Hari to everyone, including the pariah, and embraced them all. A brahmin without this love is no longer a brahmin. And a pariah with the love of God is no longer a pariah. Through bhakti an untouchable becomes pure and elevated."
