It is not the brain, that’s for sure. Some people may think that the mind is the brain. The brain is a physical object that can be seen with the eyes and that can be photographed or operated on in surgery. The mind, on the other hand, is not a physical object. It cannot be seen with the eyes, nor can it be photographed or repaired by surgery.
In Buddhist scriptures, our body is compared to a guest house and our mind to a guest dwelling within it. When we die, our mind leaves our body and goes to the next life, just like a guest leaving a guest house and going somewhere else. Biblically, the mind is simply the “inner being” or the sum total of all our mental, emotional, and spiritual faculties, without drawing fine distinctions between them. https://www.gotquestions.org/what-is-the-mind.html
The mind is that which is responsible for your thoughts and feelings. It is the seat of the faculty of intelligence and reason.
It is also commonly referred to the seat of human consciousness, the thinking-feeling 'I' that seems connected to the body but is also appears to be separated from the body.
The mind filters incoming information, so your perception is always going to be subject to deletions, distortions and generalisations.
It's the only way you will notice what is going on around you, what patterns are happening that you can use, what results you are getting, and when you need to change what you are doing.
According to Freud, consciousness is only a small portion of mental processes and that consciousness and mind are not synonymous. Consciousness is "experienced" information flow.
We may think that our suffering is caused by other people, by poor material conditions, or by society, but, it all comes from our own deluded states of mind.
The essential point of understanding the mind is that liberation from suffering cannot be found outside the mind. Permanent liberation can be found only by purifying the mind. Therefore, if we want to become free from problems and attain lasting peace and happiness, we need to increase our knowledge and understanding of the mind. We need to learn how to recognise and abandon states of mind that harm us and to replace them with peaceful and beneficial ones.
For a long time now, governments have been playing with our minds. Maybe you don’t think so or don’t realise it. Check out these articles:
The UK government set up the Behavioural Insights Team for the specific purpose of using applied psychology, including NLP, to change the views, values and behaviours of you and me. https://www.bi.team/
The government developed ‘Mindspace’ to influence behaviour through public policy. This means that we may not fully realise that our behaviour is being changed or how it is being changed. https://www.instituteforgovernment.org.uk/publications/mindspace
Then there is NESTA which is "an innovation charity with a mission to help people and organisations bring great ideas to life." https://www.nesta.org.uk/
The government is playing with our minds and has been doing so for a long time. These are horrifying assaults on one’s mind and done in such a stealthy way. We are slowly being reprogrammed and conditioned so that we can be controlled more easily to do what they want us to do. It is happening already.
Taking time out to contemplate or meditate can help to declutter and clear the mind. It may wake you up to the realisation that what is going on is not legitimate. It may make you more aware that there is more behind what you’re being told or not told. Be vigilant.
