With sincerity and earnestness one can realize God through all religions. The Vaishnavas will realize God, and so will the Saktas, the Vedantists, and the Brahmos. The Mussalmans and Christians will realize Him too. All will certainly realize God if they are earnest and sincere.
RamakrishnaYou 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.
RamakrishnaCommon men talk bagfuls of religion but do not practise even a grain of it. The wise man speaks a little, even though his whole life is religion expressed in action.
RamakrishnaDifferent people call on [God] by different names: some as Allah, some as God, and others as Krishna, Siva, and Brahman. It is like the water in a lake. Some drink it at one place and call it 'jal', others at another place and call it 'pani', and still others at a third place and call it 'water'. The Hindus call it 'jal', the Christians 'water', and the Moslems 'pani'. But it is one and the same thing.
RamakrishnaGod in the form of the saint, God in the form of the sinner, God in the form of the righteous, God in the form of the unrighteous.
RamakrishnaA man develops a subtle power as a result of the strict observance of celibacy for twelve years. Then he can understand and grasp very subtle things which otherwise elude his intellect. Through that understanding the aspirant can have direct vision of God. That pure understanding alone enables him to realize Truth.
