We say that if Krishna is truth, the world is also truth because the world is a manifestation of Krishna's energy. So if Krishna is true, how His energy can be false? The Mayavadis preach so-called monism, but they always distinguish brahma and maya. They say brahma is true, maya is false. We say maya is true, and because it is Krishna's energy, she must be employed in Krishna's service.
Letter to Gopal Krishna, June 5, 1969
