Velkyn - Scientifically measurable and applicable to me means I can - on my own - follow a procedure and get the same results consistently each time, (once I've become disciplined). Also, it means I can observe it in others who follow the same steps. While that part is more difficult, I can only really on other written sources and/or having dialogue with people who, seperately, have experienced the same results. Mouravieff was able to give more physiological explanations. He explains what one can expect to experience and why this is so. The Worthington website explains this in terms that the bible student will understand. Mouravieff explains it in a way that the esoteric student (for lack of a better word) will understand.
Having begun the steps, (and it is a continuous work), I am experiencing exactly the things that both separate sources say that I will. It is, I feel, both a spiritual as well as physiological experience at the same time; which is why - for me at least - both approaches are helpful in my learning.
However - I don't think it's the same thing as gnostic Christianity, though I think there are similarities, just as there are similarities, (or seem to be), in other religious teachings.
Hermes - I have no idea if any have improved on these techniques as I have a very hard time finding anyone willing to try to try to approach their faith in any new way. I think this is because, it may take an event of some sort, in a person's life that causes them to feel they must question their beliefs. That's the way it happened for me; and I've read of others who experienced the same shift in faith after a traumatic event.
However, I have met someone whose experiences seem to match what I have been learning. I met her on youtube and, after some correspondence, and subscribing to her videos, I believe that she is talking about the same experience and concept as the other sources.
I don't necessarily come to the same religious conclusions as her, but, maybe as I go further along, my thoughts will change. The thing is it is pretty much a universal teaching, for the most part, and I guess I like that the most about it.
As for whether or not reading the documents and discussing them being enough - the information is about applicable technique - so reading is not enough. Following procedures along WITH the understanding that comes from reading or learning is needed.
