The method of weight loss is easy to understand, but practicing it is often not..
In advance - TL;DR
I agree, but it's also important for me to offer at least an alternative perspective on the matter, and to back said alternative with sound logic and empirical evidence.
Basically, my assertion has been that most psychological disorders behave in like but to varying degrees when influenced by external and internal catalyst.
Yoga,Prayer,Meditation,Hypnosis,Talk Therapy are methodologies which employ both in the hope of coming to a more let say... sane perspective.
Often the initiation of this process is something of a more superficial nature such as wanting to lose weight, wanting to quit smoking, wanting to stop drinking or drugs, wanting to stop feeling depressed.
All expressions of more base problems within a person. Oral fixation, repressed trauma, etc.
While causality certainly plays a role here I think the "Gabriel Method" is exactly what I said from the start - brainwashing. Throw in some voodoo reasoning, mix in some psychoanalytical technique, and then let people do what they already know how to do which is eat less and exercise more and then claim supreme understanding. Solid technique - works well on dummies I bet.
That being said -
I would also say that their is no such thing in my opinion as an objective reality apart from the observer.
As it is impossible for anything within the Universe to get outside of the Universe so as to look back at the Universe I find it very unlikely that any person at any level of consciousness can say that they have a way of quantifying an objective reality.
Therefore, I agree that everyone is stuck within their own subjective perspective influenced in part by nature and nurture, but that doesn't preclude one perspective from not being wider than the other.
We often think of some of the more ignorant people we meet as narrow-minded, and having "tunnel vision", but in reality we all have tunnel vision. Some more so, some less so.
I also agree that changing someone's beliefs by attempting to change their logic and reasoning has been proven to be futile. The alternative method is of course long term degradation of their belief system (which happens naturally, as people are apt to change dramatically over the course of their lives), but that would be an abuse of the person in what could be the worst possible way. There is much unforeseen consequence in tampering with another persons base psyche without proper instruction from a trusted individual who is giving personal care to each individuals specific case.
I don't see that in this case at all, and it's kind of disturbing.
