As you can read in article "UEF: Universal Life Energy", there is no just one term that is used consistently to label the field of study into energy. With the emerging and increasing research and study into energy by our modern day scientists, the terminology in fact has increased. So too with the simultaneous growing popular (re-)acceptance of this phenomenon, writers and speakers use interchangeable terms and phases while trying to describe probably the very same thing: Universal Energy Field, orgone, Unified Field, Universal Intelligence, quanta, and so on.
At times, this may seem unsatisfactory and even confusing, but maybe it is just natural. Perhaps the plethora of terms and labels is an indication that this field of knowledge has not reached maturity. General populace, healers, and scientists alike are struggling to come to terms with the concept of what really makes up the universe. It is a large and more encompassing "thing" than just the study of an atom or a particle or gravity.
Our language develops as an idea or concept grows into multiple forms of applicable, recognizable "physical" reality. For most of us in the world, snow is snow. For skiers, there are different grades of snow and they have terms to label each state which means very specific things to them. For the Eskimos whose very existence and lives depend on that very substance, they have 24 labels to describe snow, each with subtle differences that to most of us would not be obvious and might not even make sense.
And it was not so long ago that our modern, everyday terms would have been complete unknowns and jibba-jabber to our parents as they grew up. In the earlier part of the twentieth century, who would have known what"world wide web" meant (is it a big spider web that covers the earth?), or e-mail (Like in "Eek - there is mail"?) or to "google" (is it making googly eyes at someone?) or "blog" (is it a blob of something but longer?). But each of these names/labels/terms has become our everyday language as the application and knowledge of the underlying source matured.
And so too, as our knowledge of what HEF is and means, in abstract thought as well in personal meaning and verifiable experience, our terminology of this phenomenon will also mature to be more precise. As Barbara Ann Brennan says, "As more individuals become consciously aware of these creative experiences, I'm sure that we will add the words we need to communicate better about them." (Light Emerging, 1993, page 13)
This might be true notwithstanding the fact that the study and teachings of Energy fields goes back thousands of years. Perhaps it is like I said above, it is the expanding use and acceptance of a theory or law that makes the accompanying terms and labels mature into general recognizable terminology. It might be like the "100th monkey syndrome" so that when a concept/idea has spread to an optimum level, we will find ourselves having just one (or fewer) term to express the same thing.
Or perhaps we will always struggle with a one-term label for it. Just like we do with the concept (or reality) of God (or god). Each religion calls their godhead by a different name - though many, as I do, believe that they all point to the one same source. So in a sense, the religions have "divided" up One United Source into different names which acts as a "window" through which they can conceptualize and see (their) god. Or perhaps, it is because god or energy is so vast and unknowable that we as humans in our current state of evolution, cannot grasp the entirety and our varying names and definitions is but a reflection of that truth.
