I'm still considering just how I should approach this concept.

I thought i would at least get the ball rolling on "isi". As i understand it, this word has the meaning of "contents" in Bahasa Indonesian and in Javanese i found the definition as "filling". These are similar, though not identical concepts.
I do not wish to interject my own feelings about "isi" at this point, however, here are a couple of links that approach the subject. I do not present these because i am convinced they are correct. Rather they are intended simply as fuel for the fore so to speak, to get the conversation going.
The first link is a short video by David Gallas about how to connect to the isi of a blade. I do not know if David is a member here, but i have encountered him in online keris chat groups on Facebook. Again, i am not suggesting David's take is right or wrong, but simply presenting it for discussion.

This second link is a section of Jan Mrázek's book "The Visible and Invisible in South East Asia" where he discusses the concept of isi as related to the keris. Hopefully these two links will provide a starting point for our discussion of the concept.
