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.
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.
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 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.
