Sri Ramakrishna: "Brahman is beyond vidya and avidya, knowledge and ignorance. It is beyond maya, the illusion of duality.
"The world consists of the illusory duality of knowledge and ignorance. It contains knowledge and devotion, and also attachment to 'woman and gold; righteousness and unrighteousness; good and evil. But Brahman is unattached to these. Good and evil apply to the jiva, the individual soul, as do righteousness and unrighteousness; but Brahman is not at all affected by them.
"One man may read the Bhagavata by the light of a lamp, and another may commit a forgery by that very light; but the lamp is unaffected. The sun sheds its light on the wicked as well as on the virtuous.
"You may ask, 'How, then, can one explain misery and sin and unhappiness?' The answer is that these apply only to the jiva. Brahman is unaffected by them. There is poison in a snake; but though others may die if bitten by it, the snake itself is not affected by the poison.
"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."
