Dear David,
This is yet another classic case of East Vs West. As I had written earlier, in Malay or Javanese culture for that matter, knowledge is to be sought thru certain customary ways - we cannot simply go to a guru and ask a lot of questions. OTOH, in western cultures, you are very encouraged to ask a lot of questions. So, you know how difficult it is to gain knowledge (esp if it involves mysticism, spirits etc) from a traditional Malay / Javanese guru. This is exactly what I am going thru now as I live in the very same culture, hence I am in the forum - to exchange knowledge. There's so much to learn in a very limited life span. Life is just too short.
Mr Sepokal,
Your wish will be my command. I promise not to quote your name again without permission, but I hope you reconsider stopping your inputs here

Mr Rahman,
I do not want to be drawn to yet another old debate from another forum. If you could check again in the kampungnet thread that you had dumped to the bin, I believe you would understand what Sepokal (sorry for using your name again) had said about the possible Islamic origin of the keris.
Methink, Persians (Aryans) were known to be among the first who used damascene pattern forging of weapons. They also used wavy swords - but to accommodate the local environment, the wavy damascened swords had to go thru evolution, hence the keris we see today. Of course, this theory is not absolute, but logical.
