All I know is that there is actually no subconscious or unconscious mind and that you are not your mind. You have body, you have you, and you have your mind which is just a collection of memory and information that can greatly limit you or program you in certain ways etc. You growing mentally, and collecting more knowledge and information actually means nothing, you memorising any kind of advanced knowledge or information means even less. You enhancing your intelligence so that your perception can perceive, understand and come to that same knowledge yourself through contemplating and right use of the mind is everything. This is true intelligence. Many great scientists discovered something and now you learn it in school and believe yourself to be equally intelligent but in most cases the discoveries would have not even crossed your realm of thought.
Now since we are not psychic developed enough and are mostly mere thinkers we do not access a big part of the mind, the awareness and life is lacking for us to use the full comprehension of the mind, hence science has compartmentalised our mind into conscious, that which we are mostly aware of and the basis of our daily interactions with our mind the world around us, then the subconscious which is more like a door, tunnel or pathway between the conscious and the unconscious. Think of you going into your attic and finding a box of pictures from the past and suddenly accessing long buried memories, without a trigger like a picture or something else you do not access certain layers of information. From within the mind, you exist, your emotions, deep feelings and your alivenessness, the more alive you are, the more aware and conscious you are most likely the more you can access of your mind as everything because more fluid as your consciousness and intelligence expands.
