There is fear. You are afraid of your wife; you are afraid of death, afraid you might lose your job. Will any theory, concept, help you to get rid of those fears? You can escape from them. If you are afraid of death you can escape from that fear by believing in reincarnation, but fear is still there. You don’t want to die, though you may believe in all kinds of stuff, the fact is that fear is still there. Concepts do not help to get rid of fear.
