What 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.
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.
Ramakrishna
