But then, it depends on if the teacher him self is telling the truth. False ideas, manmade hopes, and what appears to be the truth can hurt many people. But, many people like illusions, dishonesty and half truths. Sometimes things sound so good that we think it is the truth. Truth many times has to be cloaked because people can't honestly deal or handle the truth.
Truth is often times uncomfortable.
So, we live with what we can handle. People don't want to take the time to learn how to let go of limited mindsets, preconceived notions, attitudes, beliefs or values. We don't have the time, patience, perseverance or courage. The outer world stimulates us overwhelmingly. We find ways to become easily distracted.
