For some background on the Advaita saint Sir Ramakrishna (1836 – 1886 CE) see this earlier post.

Will you tell me one thing? Why did you harp so much on sin? By repeating a hundred times, “I am a sinner”, one verily becomes a sinner. One should have such faith as to be able to say, “What? I have taken the name of God; how can I be a sinner?” God is our Father and Mother. Tell Him, “O Lord, I have committed sins, but I won’t repeat them.” Chant His name and purify your body and mind. Purify your tongue by singing God’s holy name.

Translation Swami Nikhilananda
