Sri Ramakrishna (to Vijay): "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."
