This really depends on what you trust as your base source(s) of knowledge. The goal of mysticism is to see for yourself what's going on behind the curtain of apparent reality, rather than to take someone else's word. As such, it's entirely subjective. But mysticism therefore requires that you ultimately trust your own subjective experience more than you don't. I know I do, because ultimately, it's all I've got; the entirety of existence as I know it occurs completely within my mind. When it comes to matters of ultimate reality, I'm going to wager that my own intuition and some of the extraordinary experience I've had actually point the way, and are not just delusions. If I ultimately lose this wager, so be it, but I'm sticking with it.
Surely though, your experiences are judged and filtered through your own reasoning, and are relative to what is rational. I trust my own experiences only on the basis that they are rational. If I took a bunch of mescaline and had a conversation with some supernatural entity, I would obviously conclude that the entity was a figment of my imagination primarily induced by the neurological reaction of mescaline. Mescaline does not possess any supernatural powers to bring one closer to the "truth". If anything it brings one closer to understanding ones mind. So if I were to take the route of a scientist, I would propose many theories as to my experience based on rational assessment. As a mystic, I would go about things such as claiming to have transcended this or that and saw the "truth". The scientist listens for the universe whereas the mystic has the universe speak to them.
To me, mysticism longs for infinity, non-causality, and non-identity through death. Despite whatever unintelligible causes they ascribe to their incommunicable feelings, whoever rejects reality in a sense rejects existence. And in a sense their motives from then on are hatred for all the values of man and they wish to see it all destroyed. It seems as if they relish the spectacle of suffering, poverty, subservience, terror, etc. as it gives them proof of the defeat of rational reality and a feeling of triumph.
Mysticism has experience as its evidence, but is not based on any sound reality of which to call it anything other than a phenomenon, it is closed minded and selective. Many things in science might not be able to be understood at first, but its attempts are to be relative to objective reality and non-contradictory. If there is a contradiction, it is acknowledged and followed by further investigation, that's why science proposes theories.
