I had also once thought that all the knowledge we need emanates from ancient Egyptian wisdom or pre-flood civilizations but there's more to the story.

My gut feeling is that science, a field/method of study that I personally have many problems with, is fundamental in this discussion. While I don't think it would generally be necessary, I feel that we've been so inculcated to interpret reality under a scientific perspective even if we try as hard as we can to shake it off. In other words, it has contaminated our pursuit of knowledge so the best thing that can be done (again, my opinion) is to understand it in order to a) become aware of our inherent biases of its perspective and b) use it to any advantage(s) it offers us.

I encourage you to provide a definition of the quantum body and, if you could, describe how we would use this quantum body to find answers about pure being.
