Your opinions would be more creditable if you refused to indulge yourself in speaking in certainties where no certainties exist. For instance, to say that mystics "see things as they actually are" gains you no creditability except with the gullible, for you cannot possibly know that for certain. I am very disappointed in you and others in this thread who should know better than to claim for themselves more certain knowledge than they can possibly have. It's intellectually shameful.
I know this was not directed at me as you were responded to godnotgod, but I'll make some comments to it that may help.
I can't speak for godnotgod but only for myself with this, but I agree that to speak in absolutist language is a turn-off. I have said many, many times that mystical realization is not a comprehension, but rather an apprehension, which by definition leaves uncertainty in it. That said however, to say one has experienced the Absolute, is not to claim it as "a truth" that they know and all the other poor suckers just can't comprehend like you do. It's not that at all. It can only be spoken of at best in metaphoric language, not absolutist language, not dogma and doctrines. This makes it much different than religious dogma, or those who take the models of science and claim them in absolutist terms as well.
Try to think of it in terms of Truth versus truths. That Truth, with a capital T is not "a truth", but rather the nature of all truths; it itself not being a truth. To experience Truth, is to experience a certain light of revelation that illuminates all truths, while it itself is not a truth you comprehend. This is what is meant by saying Reality, or the Absolute, or the One. They are not a thing (note how the language cannot convey this).
As for mystics saying "see things as they actually are", I don't think that is a stretch, but it is not claiming an informational sort of knowledge such as a special science. It is simply meant as an expression of pulling back the curtain of illusion. Compare that on one level to being in a relationship with someone in your life, for years and years that is unhealthy but you can't see it. Then one day when the circumstances are right for you emotionally, psychologically, relationally, etc, the curtain is pulled back and you "wake up!". Suddenly it becomes clear!
It's like that, except its to how you have been living inside your head in your perceptions of yourself and the world at large. It's a waking up to the fact you've been asleep the whole time! Literally, that is what that experience is like, and hence such language as "seeing things as they really are". It's not a bold claim to specific scientific knowledge, but a
perceptual awareness.
Does that make sense?
Now, I'd love to go down the path of postmodernisit studies that actually support why and how such illusions of the world are created by our minds that supports how and why such "awakenings" occur in mystical experience, and I'd be more than happy to do so as I find it immensely cool. But the point of this is to try to overcome the sorts of reactions people have in hearing language used to take that as it is meant in absolutist terms, such as religious dogma or scientific dogma. Nothing could be further from the truth. The Absolute is infinite, and therefore impossible for anyone, mystic or otherwise to comprehend.
