Evidentally, one doesn't have to be a member of Eckankar to know, or speak about this.
Some examples:

3.)
According to the Eckankar glossary, the term Eckankar means "Co-Worker with God".[1] Eckankar is described as "Religion of the Light and Sound of God". Eckankar has also been described as "The Ancient Science of Soul Travel," "The Religion of New Age", "The Science of Total Awareness," and "A Way of Life". The main Eckankar webside has, since 2011, changed the description from "Eckankar, the Religion of Light and Sound of God" to "Eckankar, Experience the Light and Sound of God." ECK is another word for the Holy Spirit, also known as the Audible Life Current, Life Force, or Light and Sound of God.[2]:55

Those were only a few examples. No doubt there are more. And yet, terminology has changed over the years ... where once long ago Paul Twitchell used the term bilocation. The number of people speaking on "bilocation" is enormous. Just go and search YouTube for keyword bilocation.
For me, the words "ancient" and "science" are interesting - even though those are not the most modern terms used to describe Soul Travel today.
I want to look at the history of this "ancient science", or Soul Travel as it was described in Eckankar literature.
Begin here:
"The Soul Traveler system was initiated, or was first known in our records of spiritual travels, by Zoroaster, the Persian avatar, some few hundred years before the coming of Christ." [Based on: ECKANKAR, Compiled Writings, Vol. 1 (Copyright 1975 by Gail T. Gross), by Paul Twitchell, p. 43]
"No written instructions had been put down for the followers of ECKANKAR, nor any part of it, until the sixteenth century when Kabir, the Hindu mystic poet, took it upon himself to unwrap the mysteries of the ancient science of Soul Travel." [Based on: ECKANKAR, Compiled Writings, Vol. 1 (Copyright 1975 by Gail T. Gross), by Paul Twitchell, p. 59]
"From Kabir's day those who have helped spread the doctrine of bilocation were mainly, the leader of the Sikh order, especially Nanka Guru [sic], the founder. Others have been the Sufi saints, e.g., Hafiz, Jalal din Rumi, Shamus Tabriz, and Sawan Singh, Kirpal Singh, St. Anthony of Padua, and the contemporary clergyman, Padre Pie [sic], to name a few." - September 1965 issue of Search Magazine.

"[....] The THIRD PATH is a path of BILOCATION, or that which we know as SOUL TRAVEL. ... This is an Ancient Path, which came out of the misty past. There was Many, Many Centuries ago, ABOUT THE BEGINNING OF THE TIME OF EARTH, A RELIGION THAT WAS FORMED THAT CAME OFF THE PLANET, VENUS, AND WENT DOWN THROUGH THE SPIRITUAL CITY OF AGAM DES, AND THEY CALLED IT AT THAT TIME, THE NAACAL RELIGION. Anyway, it was a religion that was formed out of the SOUL FLIGHT, which has become now as ECKANKAR today. The records of this are kept in the TWO or THREE, I believe it's TWO, very remote monasteries in TIBET, in which they have not been invaded by the Chinese yet.

"[....] In a sense, Christianity has failed mankind but it is now beginning to see light and the true teachings are gradually making headway in the west. Man hardly knew anything about Eckankar, the secret science of Soul Travel, or about Bani, until the Eshwar-Khanewale adepts started making their presence felt in the world of man.

"Paul got into his early efforts to present the teachings of ECK even before he called them ECK and Eckankar. He started with weekly lectures to small groups of fifteen to thirty people at the California Parapsychology Foundation in Southern California. In those days he referred to Soul Travel as bilocation, and it was explained as a way to reach the Supreme Oneness. He was trying to express the Sugmad, the Supreme Being, and that the way to It was through the Voice of God, which we know as ECK."

There was another example where I thought I saw the words soul travel in a book printed years before Eckankar was founded; thought I posted the link here but I can't seem to find it.
In any case, I probably can agree that history and stories of people traveling via "Soul Body" is somewhat ancient. It's not like Eckankar has any kind of a monopoly on the idea. Others have described this too. And when "Dream Travel" is added into the mix I believe it fair to say this has been around for ages too. Iow, there have been stories written about this kind of thing for centuries. If one is looking for the "ancient science" though, and a record of that recorded throughout history, I think one has to naturally sift the fictions from the facts in order to get the best understanding about what that ancient science truly entails.
