Radhanath Swami explains the illusion beautifully, “This world is real and you are real. Anything that emanates from God is real because God is real. You are an eternal soul, but when you identify yourself with the matter of this world, that is an illusion. When you think your happiness is to enjoy matter that is an illusion. That is the source of all bondage. But when we see matter and think of how to use it in God’s service, that is knowledge.” .
