“But would you kindly ponder this question: What would your good do if
evil didn't exist, and what would the earth look like if all the shadows

of your fantasy of enjoying naked light? You're stupid.”
― Mikhail Bulgakov, The Master and Margarita

“There is no greater misfortune in the world than the loss of reason.”
― Mikhail Bulgakov, The Master and Margarita

“Whatever our souls are made of, his and mine are the same”

― Mikhail Bulgakov, The Master and Margarita
