I was in a place about two years ago where I gained great knowledge about the mind. In the diagram of the two circles intersecting, I was taught that the left part of the circle represents our Reasonable Mind.
The Reasonable Mind (head) is thinking from an intelligent, logical and rational place. This is primarily based on facts, data and knowledge. Behavior is mainly planned, focused, calm and distant. Reasonable Mind is generally absent of emotion. Decision-making and problem solving from Reasonable Mind would be comparable to a computer making your decisions and solving your problems.
The left side of this diagram is the Emotional Mind (heart) is thinking primarily from an intense feeling position. Thoughts, information and facts are processed through intense emotion causing both inaccurate and distorted perception. Behavior is congruent with your current emotional state.
The part of this diagram which is in green is the Wise Mind. Wise mind combines both reasonable mind and emotional mind abilities. Decision-making and problem solving can be done with intelligence, logic, facts and feelings. Wise mind also adds your intuition. Wise mind helps you distinguish which aspects of your feelings, facts, and intuition are from the past and which parts are from the present.
To learn how to be in the wise mind, which is not associated with our ego is...1. to recognize where you spend most of your time IE:...in the heart or in the head. 2. to be able to learn what the wise mind is to you. A Wise Mind can be: compassion, curious, calm, cool, collected, confident, have a sense of equality and be comprising.
To be in the Wise Mind is to be in the Now. A good exercise to practice being in the now and controlling your ego, is to take yourself to a quiet place. Try to be in the now and make your mind blank. As you do this, you will get random thoughts in your mind. This is your ego, as it is used to being there and butting into your quiet mind. The longer you practice this, the more you will find you are in control of your mind and not your ego, as you will learn to be in the now and quiet the ago from interrupting this space in time. You will progress as each time your ego pops in...start the exercise over. Start slowly and each day you will find the ego will not interrupt your thoughts has you are learning to manage your ego and to make it still so you can be in the now and one with yourself and your Wise Mind will surface more easily than you ever imagined.
Eckharte Tolle has a wonderful book on being in the now and teaches you wonderful things about being in the now that will open flood gates to your consciousness.
When we give opinions, that is our ego speaking mostly and not our Wise Mind. I continually have to back up and get back to my Wise Mind, as the ego is very strong, and doesn't like to be kept in check, but we, as individuals can learn to control the ego, as it was formed by society, upbringing. religious teachings and other methods. Our Wise Mind is being in touch with the reality of real life and a higher Source.
I do hope this helps, as when I learned this, it took much practice, but I did eventually master my ego...sometimes it still comes out and I need to put in back in its place. This is by no means something easy to master, but I know you have the will to do this.
