“Man cannot really help the world. God alone does that”
He who has created the sun and the moon, who has put love for their children in parents' hearts, endowed noble souls with compassion, and holy men and devotees with divine love. The man who works for others, without any selfish motive, really does good to himself. There is gold buried in your heart, but you are not yet aware of it. It is covered with a thin layer of earth. Once you are aware of it, all these activities of yours will lessen. … Through selfless work, love of God grows in the heart. Then, through His grace, one realizes Him in course of time. God can be seen, one can talk to Him, as I am talking to you.
As quoted in Ramakrishna : Prophet of New India (1948) by Swami Nikhilananda, p. 80

“And if God does not help me to go on, then I shall have to help God.”
The surface of the earth is gradually turning into one great prison camp, and soon there will be nobody left outside. … I don't fool myself about the real state of affairs, and I've even dropped the pretense that I'm out to help others. I shall merely try to help God as best I can, and if I succeed in doing that, then I shall be of use to others as well. But I mustn't have heroic illusions about that either.
