Thank you Boedhi Adhitya for your clear and concise explanations. As usual you have shed some light on a very complex subject. And thank you for the definitions as well.
Your words make a lot of sense to me.
Purwacarita, it seems to me that the man making his keris cut grass for the TV cameras is more likely using slight-of-hand or some other stage magic technique than the more esorteric explanation that he has mastered some prana energy.
He is most probably a chalatan, not a holy man. IMO dogs can be made to do "tricks", but keris should not.
I am curious about your use of the terms Yoni and Lingam (lingga). These are Hindu terms of Sanskrit origin with rather particular meaning. They refer specifically to the venerated symbols of the female (goddess) and male (god, specifically Siva) genitialia as it applies to the Hindu religion. From what source are you making your adaptations of these concepts to the keris? I am not saying one way or another is i believe this application is correct, but i would be interested to know what you base it on. I do find the use of the term Yoni to mean "esorteric" a bit vague.
