You must drop all that you think you know, for true wisdom will never come to visit you if you hold opinions and judgements about anything.
False knowledge is akin to giving a child a loaded gun to play with. Unless you learn to think clearly, your mind will be led astray by every contrived thought that enters your mind.
First you must drop all that you think you know! You have gained false knowledge like many people, since you were a child. Your thoughts and opinions have been tainted by your parents, your teachers, family and friends.
