 The fear is simply because you are not living with life, you are living in your mind. Your fear is always about what's going to happen next. That means your fear is always about that which does not exist. If your fear is about the non-existent, your fear is hundred percent imaginary. If you're suffering the non-existential, we call that insanity. So, people may be in just socially accepted levels of insanity, but if you're afraid or if you're suffering anything which does not exist, it amounts to insanity, isn't it? People are always suffering, either what happened yesterday or what may happen tomorrow. So your suffering is always about that which does not exist, simply because you're not rooted in reality. You're always rooted in your mind. Mind is one part of its memory, another part of its imagination. Both of them are in one way imagination because both of them don't exist right now. You're lost in your imagination, that's the basis of your fear. If you were rooted in reality, there would be no fear.
