There is on-going activity within each of our "invisible worlds" (in layman's term I termed it spiritual). Every one of us has the ability to analyze any situation or problem i.e. entertaining what we see, hear or feel, recalling the memory of "what happened", to a visible state where we express sadness or happiness, anger or satisfaction, some of us may even conceptualize on day-dreaming (particularly common among young people). There are ever changing feelings and emotions about everything we experience in life, and an endless parade of prejudice, judgments and perceptions about what we see occurring. Actually, for many of us, we dwell too much on the mentality. It goes on and on and never seems to stop. In our minds, there is a constant relay of images, memories and ideas intruding themselves upon our awareness and translated into our expressions or consolidated emotions. Most of us can't control any of this and simply accept as inevitable moods of our lifestyle.
In a very real manner issues brought to our attention, and in psychological aspects we named them as "depression (oppression)", "anxiety", "compulsive disorder, ADD/ADHD, *****T and even "suicidal", are ultimately and if uncontrollable in one's own mind that intrude upon the physical reaction. Apart from this fact, I believe in some way, as lay people, we understand and claim to resolve them in a way we know best. A better way to handle these problems would be to assist the person to manage the content of his/her own mind. There are other ways to do this, for some, the spiritual enlightenment is based on the individual beliefs and experiences although they have never been all pulled together, adequately investigated, codified and organized into a straight-forward workable compilation of methods. Modern "science" has simply discarded the notion of the spiritual mind, and from that point on, never bothered to investigate it with the aim to understand, or comprehend the powerful invisible domain within each person.
It is impossible to comfortably observe one's own mind (because it may possibly be filled with degraded concepts), and probably subject to the physical five sensations and society expectation/perception to the exclusion of anything in the invisible world. To put it simply, our mind dwells on the intellect, awareness, logic, will power, responsibility, info and
and many other things known or unknown exist in us. Some people might say these things are evolved into our existence - we are born this way. There is much to each of these areas of researchs and my short essay here cannot begin to even scratch the surface of the nature of how our mind is functioning, possible development and capabilities. But our beautiful mind definitely exist in our everyday life. Any subject calling itself "psychology" would have to address these things in detail. The failure of modern psychology to do so is glaringly apparent. It only addresses outward human behavior, physiology, genetics and biochemistry, and the mind is of no real concern to us individually. It is highly controversial on the current state of clinical therapy where modern science followed this same vein and more details can be found on the subject of Scientology if you are keen.
