If we introspect on what the mind is, we come to the conclusion that it is different from the body. We are tempted to believe that the mind is some sort of a function of the brain. But the brain is also completely a physiological organism, at the most it can do certain things that are "programmed".
Similar to the concept of Inverse Kinematics familiar to 3D animators, there are programs in the brain for all the functions of the body. It might also appear to create thoughts. or show certain activity associated with thoughts, emotions etc.
One can say, there are neurons, that keep firing all the time, and there is chemical, physical and physiological actions going on in the brain. One may even eventually "identify" through some sort of a scanning mechanism a single particular thought, or a unique configuration of the brain or part of it, while one has a certain thought. We may even be eventually map all thoughts by physical observation. So what does it mean? is the brain responsible for our thoughts?
The unique distinction between a programmable computer such as a Turing machine, and the human is that there is somebody "having", or "observing" the thoughts. In the case of the computer, there is none.
The true "I" does not belong to this place of physical reality at all. what we see in this world is a representation of the real I. Just like we observe our self as a character inside our dreams.
The most difficult part of handling our lives surround around how our mind functions. What it does, feels and how it emotes. If we realize that the mind belongs to the lower order of reality, and we are able to observe it, since we know what the mind thinks, we can ease a bit, saying I am not this suffering mind at all. I am simply an observer of it, just like I am the observer of my body.
However this is easier said than done. Just like the body has characteristics, the Mind has its character. the mind, just like the body and like every other thing in the Universe, is made of three kinds of nature, Aura, Energy and Matter.
The composition of the mind based on these three components keeps changing all the time. It depends on the food we eat, the company we keep, the books we read, the news that we consume and so on. It also depends on the time of the day, the weather, the climate, the colors and what not. and all of this varies from individual to individual. as they say one man's meat is another man's poison.
Having known this, we can try to control the composition as much as we can. But this is similar to protecting the physical body from illness, or having a high fitness level. There will always be sickness, points of break down etc.
So, the real solution is simply the knowledge that the mind will always keep changing. sometimes it is very enlightened, sometimes it is agitated, sometimes is is dull, based on which nature is dominant at the moment.
Just realize this fact and simply observe when the mind is in what nature. When is Aura, enjoy and make the most of it. when in Energy get your things done, when in Matter(dullness) just laugh it out.
This knowledge, similar to the knowledge of the changing seasons, liberates and ends suffering.
