It is on account of the ego that one is not able to see God. In front of the door of God's mansion lies the stump of ego. One cannot enter the mansion without jumping over the stump.
RamakrishnaYou see many stars in the sky at night, but not when the sun rises. Can you therefore say that there are no stars in the heavens during the day? Because you cannot find God in the days of your ignorance, say not that there is no God.
RamakrishnaOnly two kinds of people can attain self-knowledge: those who are not encumbered at all with learning, that is to say, whose minds are not over-crowded with thoughts borrowed from others; and those who, after studying all the scriptures and sciences, have come to realise that they know nothing.
