The ego is unreal; brain cells are not unreal. Ego is unreal; memories are not unreal. Ego is unreal; thought process is not unreal. Thought process is a reality. Memories are real, brain cells are real, your body is real. Your body is real, your soul is real. These are two realities. But when your soul gets  identified with the bodies, the Ego is formed – that is unreality.
It is  just like this. I am standing before a mirror; I am real, the mirror is real but the reflection in the mirror is not real. I am real, the mirror is also real, but the reflection in the mirror is a reflection, it is not a reality. Brain cells are real, consciousness is real, but when consciousness gets involved, attached, identified with the brain cells, the ego is formed. That ego is unreal.

So when you have awakened, when you have become enlightened, you memory is not going to disappear. The memory will be there. Really it will be more crystal clear. then it will function more accurately because there will be no disturbance from the false ego. Your thought process will not disappear. Rather, for the first time you will be capable of thinking. Before that you were simply borrowing things. Then you will really be able to think. But then you, not the thought process, will be the master.
Before, the thought process was the master. You couldn’t do anything about it. It continued on its own; you were just a victim. You wanted to sleep and the mind continued thinking. You wanted to stop it, but it would not stop. Really, the more you tried to stop it, the more stubborn it became. It was your master. When you become enlightened it will be there, but then it will be instrumental. Wherever you need it, you will be able to use it. Whenever you don’t need it, it will not crowd your consciousness. Then it can be called and then it can also be stopped.
Brain cells will be there, the body will be there, memory will be there, thought process will be there. Only one thing will not be there – the feeling of ‘ I’ will not there. This is difficult to understand.
