So Nick, you asked... WHAT IS THE PURPOSE OF THIS EXISTENCE?
In the most basic sense, the purpose of life is being - as opposed to not being.
In your system of three-dimensional reality you are learning about mental energy (also called thought energy or psychic energy) and how to use it.
Knowledge about mental energy and its use is learned by constantly transforming your thoughts and emotions into physical form (your physical reality) and by then perceiving and dealing with the matter and events that are formed.
From doing this, you are supposed to get a clear picture of your inner development as it is reflected by the exterior environment.
You participate in physical reality so that you can operate and experience within this dimension. Here, you can develop your abilities, learn, create, solve problems and help others.
Matter is the shape that basic experience takes when it comes into your three-dimensional system.
Your dreams, thoughts, expectations, beliefs and emotions are literally transformed into physical matter.
HOW DOES THIS WORK?
Every nerve and fiber within the body has an unseen inner purpose. Nerve impulses travel outward from the body, along invisible pathways, in much the same manner that they travel within the body.
These pathways are carriers of telepathic thoughts, impulses, and desires containing all the codified data necessary for translating any thought or image into physical actuality, altering seemingly objective events.
This telepathy operates constantly at an "automatic" or subconscious level, providing communication to back up sensory data. Telepathy is the glue that holds the physical universe in position, so that you can agree on the existence and properties of objects. In one respect, your body and all physical objects go flying out in all directions from the inner core of the whole self.
The physical environment is, therefore, as much a part of you as your own body.
What seems to be a perception, an objective concrete event independent from you, is instead the materialization of your own emotions, energy and mental environment. Events and objects are actually focal points where highly charged psychic impulses are transformed into something that can be physically perceived: a breakthrough into matter.
The intensity of a thought or image largely determines the immediacy of the physical materialization. All such images or thoughts are not completely materialized, in your perception, as their intensity may be too weak.
MY INTELLECT DOESN'T HAVE THE INFORMATION TO CONTROL ALL OF THIS,
HOW IS IT HANDLED?
There is an inner ego, an inner self which organizes "unconscious" material.
As the outer ego manipulates within the physical environment, so the inner ego or self organizes and manipulates within inner reality.
It is this inner self, out of massive knowledge and the unlimited scope of its consciousness, that forms the physical world and provides the stimuli to keep the outer ego at the job of awareness. The inner self organizes, initiates, projects and controls the transformation of psychic energy into matter and objects.
The energy of this inner self is used by it to form a material counterpart (you). You then deal with the physical reality that is made and work out your own creative role.
TELL ME MORE ABOUT THE WORKINGS OF THE
"INNER SELF"
The individual inner self, through constant effort of great intensity, cooperates with other entities like itself to form and maintain the physical reality that you know.
The inner self has a virtually infinite reservoir from which to draw knowledge and experience. All kinds of choices are available, and the diversity of physical matter is a reflection of this deep source and variety.
Having determined upon physical reality as a dimension in which it will express itself, the inner self, first of all, takes care to form and maintain the physical basis upon which all else must depend -- the properties of the earth that can be called the natural ones.
The deepest, most basic subjective experience is translated into the natural elements: the ample landscape that sustains physical life.
With the natural structures formed and maintained, other secondary physical properties are projected.
WHY ISN'T THE NATURE OF ALL THIS CLEARER?
It is the daily ego's ignorance and limited focus that makes it view so-called unconscious activity as chaotic. The waking ego (dealing with physical reality) cannot know all the unconscious material directly.
The daily ego is simply not conscious enough to be able to contain the vast knowledge that belongs to the inner conscious self from which it springs. The outer ego is spoon-fed, being given only those feelings and emotions, only that data, that it can handle. This data is presented in a highly specialized manner, usually in terms of information picked up by the physical senses.
The inner self is not only conscious, but conscious of itself, both as an individuality and as an individuality that is a part of all other consciousness. It is continually aware of both this partners and unity-with. The outer ego is not continuously aware of this fact. It frequently forgets its "whole" nature. When it becomes swept up in a strong emotion it seems to lose itself. When it most vigorously maintains its sense of individuality, it is no longer aware of unity-with.
If the ego were aware of the constant barrage of telepathic communications that do impinge upon it, it would have a most difficult time retaining a sense of identity.
TELL ME MORE ABOUT CREATING AND MANIPULATING MY OWN REALITY.
You must learn to listen to the voice of the inner self and work with it. You may also simply ask the inner self to make the answers to problems available on a conscious basis.
You create your reality according to your beliefs and expectations, therefore you should examine these carefully. If you do not like some aspect of your world, then examine your own expectations.
Your world is formed in faithful replica of your own thoughts... If you think positive suggestions to yourself about a situation you send telepathic ammunition for positive use. You must learn to erase a negative thought or picture by replacing it with its opposite.
You should tell yourself frequently "I will only react to constructive suggestions." This gives you positive ammunition against your own negative thoughts and those of others. A negative thought, if not erased, will almost certainly result in a negative condition.
Say to yourself, "That is in the past. Now in this new moment, this new present, I am already beginning to change for the better." It does not do to repress negative thoughts, such as fears, angers, or resentment. They should be recognized, faced and replaced.
Recognize resentment when it is felt, and then realize that resentment can be dismissed. Initial recognition must be made. Then you must imagine removing the resentment "by its roots" and replacing it with a positive feeling.
You must watch the pictures that you paint with your imagination. Your environment and the conditions of your life at any given time are the direct result of your own inner expectations. If you imagine dire circumstances, ill health or desperate loneliness, these will be "automatically" materialized, for these thoughts themselves bring about the conditions that will give them a reality in physical terms.
If you would have good health then you must imagine this as vividly as you fearfully imagine ill health.
You create your own difficulties. This is true for each individual. The inner psychological state is projected outward, gaining physical reality - whatever the psychological state may be... The rules apply to everyone. Knowing this, you should try to realize what your psychological state is and change your conditions for your own benefit.
You cannot escape your own attitudes, for they will form the nature of what you see. If changes are to occur, they must be mental and psychic changes. These will be reflected in your environment.
Negative, distrustful, fearful, or degrading attitudes toward anyone work against the self. If an individual sees only evil and desolation in the physical world it is because he is obsessed with evil and desolation and projects them outward, closing his eyes to other aspects of reality.
If you want to know what you think of yourself, then ask yourself what you think of others and you will find the answer.
True self-knowledge is indispensable for health and vitality. The recognition of the truth about the self simply means that you must first find out what you think about yourself subconsciously. If it is a good image, build upon it. If it is a poor one, recognize it as only the opinion you have held of yourself and not an "absolute state."
You are not your emotions. They flow through you, you feel them and then they disappear. When you try to hold them back they build up.
You are independent of your thoughts and emotions. You have emotions. You use your thoughts and emotions in your mental composition.
You must learn to trust your own spontaneous nature.
Your nervous system knows how to react. It reacts spontaneously when you allow it to. It is only when you try to deny your emotions that they become a problem. In spontaneity there is a discipline that utterly escapes you, and an order beyond any that you know. Spontaneity knows its own order.
All of nature is spontaneous. Our bodies will be healthy automatically if we do not project false ideas upon them.
Action accepts all stimuli in an affirmative manner. This is why an illness is accepted by a personality structure, and once this occurs, a conflict develops. The self does not want to give up a portion of itself even while that portion may be painful or disadvantageous.
Physical symptoms are communications from the inner self, indications that we are making mental errors of one kind or another.
Do not forget that you are a part of the inner self. IT IS NOT USING YOU!
What you are supposed to do, then, is change your mental attitude, search yourself for the inner problem represented by the symptoms, and measure your progress as the symptoms subside.
You sell yourself short if you believe that you are only a physical organism living within the boundaries cast upon you by time and space.
You must accept life on its terms, and not demand that it behave in certain ways. You must accept life gladly, as its own reason and cause within you.
Life is abundant, vigorous, and strong. Each of us has our own defense against negative suggestions and we should trust in our own immunity.
You are a unique individual. You form your physical environment. YOU MAKE AND CHANGE YOUR WORLD. You are part of all that is. There is no place within you that creativity does not exist.
You must live in faith that your purpose is, and will be fulfilled. The uniqueness of your own personality is to be cherished. The particular purpose of your present personality can only be met in the present circumstances in the way that is best overall. The people that you can help now and the particular good that you can do, can never be done in precisely the same way.
Throughout the ages, some have recognized the fact that there is self-consciousness and purpose in dream and sleep states, and have maintained, even in waking life, the sense of continuity of the inner self. To such people it is no longer possible to completely identify with the ego consciousness. They are too aware of themselves as more. When such knowledge is gained, the ego can accept it, for it finds to its surprise that is not less conscious, but more, and that its limitations are dissipated.
