“The true sign of intelligence is not knowledge but imagination.” ~ Albert Einstein; German-American physicist and major influencer on the philosophy of science.
Everything you see with your mind and with your physical eyes as well, and everything you experience within and around you is made up of energy, highly conscious energy. The great buildings, the great art, computers, trees, grass, soil, clouds, air, relationships, events, humans and animals, the past, the present, the future, and absolutely everything else you can think of is born and sustained out of energy; such energy shaping and guiding it all, the energy which creates it all. And when it comes to the man-made stuff I just mentioned, like great buildings, it was first born into the mind of someone; therefore, someone saw it within his mind, moved the psychic energy around to fit a shape, quality and meaning, and compiled it into a vivid realization with a unique message for the human race, then that same mind worked with other minds and brought the mental image into the outer material world, but great imagination is always behind it all.
In human relationships, for example, there are so many arguments and disputes, bad judgements and frustrations, break-ups and divorces, all misunderstandings and misconceptions which lead to confusion, disappointment and suffering, because most of us forget or ignore the existence and higher purpose of this energy or energies; hence, the building essence of all relationships is to find a way (and there is always a way) to work together as families, friends, lovers, partners, neighbors, etc. etc., but we ignorantly use our ego (which is not even close to the energies of imagination and creativity) while believing erroneously that our reason and perspective, intellect, can always fix and enrich everything. This is our lower-thinking because it is guided by the ego and its selfishness (even though we might not think we are being selfish at the time; the purpose of the ego is to make it look normal and deceive us into thinking we are right and fair).
Imagination is not just creating a beautiful work of art or innovating with a brilliant idea, but it is knowing how to create value within your own persona and share that value with others in relationships, it is how to work out problems or issues and get to solutions in your life, and perhaps most importantly is the moving of people by connecting with them and not by enforcing your opinions or demands in a certain situation–for example, if you and your significant other have a problem and you enforce your views then there is going to be resistance and maybe even frustration in the other person; however, if you use and manage your imagination you can come up with a more meaningful way in which you can benefit both, and that can help you get a better connection in the relationship and deeper understanding of both viewpoints.
Imagination is that which builds, because it molds to the higher understanding and necessity of the human being, it is flexible and nonlinear; but reason and logic do not build, because they are strict, linear.
But the ego does not build, it deceives people into thinking reason and logic out of the ego-mind creates and designs all; however, whatever creates true beauty and absolute harmony in the world and in all your relationships is divine energy, or energy which is not flawed or bias like the ego energies of the mind. This divine energy (which is only called “divine” because it comes from far beyond time and space and the very mortality of man) is all true creativity and honest manifestation of beauty and strength, and by being shaped and given qualities by our minds then it is called imagination due to the images we form with it.
“You can’t do it unless you can imagine it.” ~ George Lucas; American filmmaker and entrepreneur.

But, you see, the imagination within our minds, or the essence of this energy, is raw, unformed, with no qualities and textures of this physical reality, because this, as mentioned above, is divine energy coming from beyond space and time (space and time is created by the movement of matter, is created by our mundane thought to fit our corporeal lives here); however, this is highly conscious and dynamic energy which is inside each cell of our bodies, each nerve, and all around us making the rich and creative substance of universes themselves, and so this means that we have to interact with it all the time to bring this raw energy into the material world and in this way design what we would like to see and experience every single day–i.e. more patience and care in relationships, money and prosperity, motivation and intention to succeed in helping and accepting others, more talents to further our own advancement in life, etc. etc.
Imagination is the moving forward of all beauty and truth through the interaction of our minds in creating peace and prosperity, love and motivation; but, this is deep understanding of the Higher Mind now, it must have our honest and dedicated effort to bring it into our lives as we wish constantly, and the issue we have to always be aware of is that we are always creating and desiring, whether we want to or not, consciously or subconsciously.
So in order to build manifestations centered in good relationships, a better financial status, greater motivation to succeed, higher visions of what you must do to better yourself, make sure your heartfelt desires and higher perspectives about yourself, others and the world around you, stay away from the deceits of your ego before you create using the greater energy of imagination.
