"If you say you have an empty mind and you don't have an empty mind, you only know later that you have an empty mind. Because if you say you have empty mind, you don't have empty mind, because you're already thinking about it."

He says, You have to study and learn so that you can make up your own mind about history and everything else but you can't make up an empty mind. Stock your mind, stock your mind. You might be poor , your shoes might be broken , but your mind is a palace.
