If you meditate on your ideal, you will acquire its nature. If you think of God day and night, you will acquire the nature of 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.
Ramakrishna
