You speak of doing good to the world. Is the world such a small thing? And who are you, pray, to do good to the world? First realise God, see Him by means of spiritual discipline. If He imparts power you can do good to others; otherwise not.
RamakrishnaWhat Brahman is cannot be described. All things in the world — the Vedas, the Puranas, the Tantras, the six systems of philosophy — have been defiled, like food that has been touched by the tongue, for they have been read or uttered by the tongue. Only one thing has not been defiled in this way, and that is Brahman. No one has ever been able to say what Brahman is.
RamakrishnaSo long as the bee is outside the petals of the lily, and has not tasted the sweetness of its honey, it hovers around the flower emitting the buzzing sound; but when it is inside the flower, it noiselessly drinks the nectar. So long as a man quarrels and disputes about doctrines and dogmas, he has not tasted the nectar of true faith; when he has tasted it, he becomes quiet and full of peace.
