Courtney Brown often defines “IS-BE” with "something that is simply for the purpose of being" yet does not reveal how he came to that understanding. I am aware the book "Alien Interview" and the religion Scientology explain the immortal spiritual being. The wording Courtney uses makes me think he's drawing from the former. Are there Farsight RV videos or any other sources that confirm this or provide evidence for the immortal spiritual being? I know some of Farsight's videos can provide valuable insights, but they're often revealed after an hour or more into a three hour video and there's a whole trove of videos I have yet to explore. I come from a place of good spirit and simply wish to strengthen my understanding of immortal spiritual beings so that I can explain it well to others.

It's from the Airl interviews. The book they are publishing soon has the information on it. One of the original aliens recovered during Roswell and was interviewed by a nurse for the military. The alien referred to herself as Airl. Maybe more importantly BEING and IS are terms used heavily in philosophy. A being is essentially a moral agent. Is means the identity property. Either the airl thing is made-up because there's obvious influences from philosophy, or Airl came up with the term IS-BE after reading lots of human literature. In the interview/story Airl spends a week or so speed reading tons of books in order to properly communicate with the nurse.

Renee Descartes' famous quote "I think therefore I am" is essentially him identifying he's an ISBE. He was trying to find a logical basis for scientific theories and all he realized was he can't justice that anything exists except for his own thoughts, and his own thoughts confirm that he exists.

The Airl story is great you should check it out.
