Interesting discussion, Gentlemen. I haven't read a series of posts as well written as Kiai Carita's for a while. Thank you and welcome to the forum, Kiai Carita.
What I'm going to write is not directly linked to the discussion above, but just some thoughts that arose while reading the posts.
While I am not a believer of supernatural or paranormal activities/powers, I do see the point that the keris in totality is anchored in more than the material world. And it is up to the individual how they want to approach the keris. So I would say Nechesh and Kiai Carita are on different sides of the same coin, and finding it difficult to see face-to-face. But that is not to say anyone is right or wrong. The world is made up of all views, just like in order to appreciate the keris, one must look at all physical angles, and then the non-physical aspects too. Some of us are 'irreconciliably' anchored in one aspect, but that is alright. Its our karma and dharma.
I think it is as important to consider how the keris is treated and perceived, as it is to look at what it is physically. The keris is a different thing as seen by different eyes, from the local Southeast Asians to the Westerners who 'veni, vidi, vici' centuries past and brought back a whole bunch of kerises to Europe (in a certain way, a fortunate outcome of an unhappy past because some of the most beautiful kerises got preserved immaculately).
Anyway, in totality, apart from the physical attributes and composition that make a keris beautiful and/or lethal, the keris has an aspect of mysticism and esoterism that is not so readily shared, understood or seen. However, just because it cannot be seen or proven does not mean it is not there (or there, for that matter). In fact, it may have never been meant to be proven. But not able to prove something does not make the thing less real. An idea/concept/story does not need to be proven. They are. (Well, if someone wants to find the exact origins, what happened to who, why the idea came up, produce evidence, etc, he could do that, but that's not the point). Just as some of these things run on 'faith', they also run on 'views'. As we may have observed, sometimes, when enough people subscribes to a view, it becomes the 'truth'.
And also, sometimes, things we cannot understand or prove is just something we cannot understand or prove. e.g. there is this man in China who can generate so much heat from his hands that he can cook a fish just holding on to it. There's this Korean master who could hold a spoonful of molten lead in his mouth. I have personally experienced a Tai Chi master who can control electricity from a live wire and allow small 'hair-raising' current to pass on to people holding onto his bare hands (in fact he could vary the current passing through). So maybe it is not too difficult to imagine people who are attuned to finding things (for whatever reasons unexplained, but not necessary paranormal/supernatural). Hey we have Jedi knights who can see into the future with the aid of the 'Force', right?
Ok, I think my thoughts are not coming together in a disciplined manner, so I better stop this verbal diarrhea.
