The great differences in density and vibrational levels also explains why we are unable to see any forms of sentient life when we send Earth space probes down onto our neighboring planets. All our Solar System’s inhabited planets, together with their surrounding vegetation and lifeforms, no longer exist on the dense physical vibratory level.

They at present exist on the 4th or 5th dimension/density on the Etheric plane, a surrounding plane of life and matter existing at a higher and more tenuous vibratory level not visible to us, even though it is perfectly solid to themselves.

When we send our exploratory space-probes to our neighboring planets, our spacecraft unknowingly pass right down through these higher vibrational planes and continue to descend down to the planet's previously inhabited physical crust, long since abandoned and which is now totally lifeless. From this we assume that there are no other inhabited worlds. We nonetheless have had many communications and visits from our interplanetary Space Brothers over the years since the end of World War II, these having been published in numerous books by some of the lesser-known esoteric publishers.

One well-known ‘contactee�?out of many, is Tuella, whose published communications from our Space Brothers include messages from the large group of interplanetary spaceships on station within our solar system, known as the 'Ashtar Command'. Amongst the many communications Tuella has had from the Ashtar Command, she at one point attempts in her book 'Ashtar - A Tribute', to clarify the nature of the different vibratory levels by inquiring of Space Commander Ashtar about the higher ‘Etheric�?vibration level on which all our neighboring Space Brothers live:

Tuella: "From your statement that you are etheric, am I to presume that you have evolved beyond the stage of a physical body?"

Ashtar: "Correct. I do not possess a physical casing of the dense type such as yours. I am definitely etheric, as are all people on other planets in this solar system. However, this does not mean that we are invisible to each other, as we are to you under normal circumstances.

We see each other and live much as you do, but we do not have this dense physical casing which you possess. The advantages, benefits and comforts of this living are enormous, and the irritations of the fleshly envelope are most uncomfortable. Unless we choose to convert the vibrational frequency of our bodies to one which is visible to your optics, we remain invisible to your people.

Nevertheless, highly evolved people, with a good psychic eye as you call it, can sometimes see us in vaporous form, although we may be invisible to other Earthlings in the same location. When your clairvoyants travel in their spiritual bodies to our civilizations on other planets, they see and are able to interpret our lives because they are not using their physical eyes but their astral or psychic sight, to which we are visible just as though we were physical."

Tuella: "I am curious about the nature of etheric matter. For example, there is one case on record where one of our jet aircraft flew right through a space ship, without hitting anything solid whatever. Are your ships made of a vaporous substance, or are they a different form of Earthly matter?"

Ashtar: "We have all the elements you know on Earth, and many more. The etheric form of metals differs in its atomic and molecular structure from Earth made metals. For example, the distance between the nucleus and the orbiting electrons of the etheric iron is much greater than in physical iron, as you know it on Earth.

This permits the atoms of Earthly steel to pass right through the atoms of etheric steel in such a way that nothing happens to either form of steel. The etheric form of steel enjoys a higher vibratory rate than Earthly steel and therefore is not apparent to Earthly vision or, if you prefer, physical eyesight.

"Because of our knowledge of Universal Law, our very being consists of a higher level of vibration than you people of Earth. You see, every particle of the Universe consists of molecules whose center contains an atom around which electrons and protons revolve. Each molecule of a different molecular structure vibrates at a different frequency. The inside of a molecule is identical in makeup to the Universe.

Planets revolve around central suns; solar systems around galaxies; galaxies, around a central universal sun. Each molecule vibrates at whatever frequency seems appropriate for our existence. "As one becomes more spiritual in nature, thinking only of the welfare of others and not of power and greed, the higher the molecules of one's being will vibrate.

As we know in our dimension, it is possible for these molecules to vibrate so rapidly that the frequency becomes pure light. This is why we call ourselves the Forces of Light. We depend on the Light from The Source -The Creator, God, for our existence."

Thus the student of New Age Thought, though perhaps unable to see or to sense the presence of Beings existing on other vibratory levels, can now at least comprehend their existence. As our evolution progresses, as we move to higher levels of being, a wider range of perception will open up to us.

But even now, indeed particularly now as we struggle through the denser realms of our evolutionary journey, an expanding awareness of higher realms can open our intuition to the many sources of guidance and wisdom available to us.

What is known to New Age thought as the 'Higher Knowledge' exists as freely available knowledge on the higher Etheric and Spiritual planes, but cannot be accessed by most of us at the physical level due to a blocking "Veil of Forgetfulness" which has been placed for our protection between us and the higher worlds. Instead, this higher knowledge is mostly communicated down to Earth by those teachers and Masters who are able to transmit their thoughts directly to a trained Earth mind known as a 'channel'.

This process is made possible on Earth through 'channelers' who have themselves undertaken training over long periods during many past lives in opening up their higher spiritual centers. However, it is important for the Earth channeler to be able to set aside any Earthly emotions and preconceptions which might otherwise color and distort the communication.

Channelers are usually able to receive channeling either by going into a state of trance, or in more developed cases, directly into the conscious mind in the form of words, thoughts, or automatic writing.
