Hello Makita, refering to a question you had asked earlier about chaos and hermetics and traditional hermeticism, here's some info for you. I'll skirt the historical aspect to keep this short, but hermeticism used to be, and is still called in some circles, hermetism, and there is a tradition although these days I think we have a tendency to think were are always creating new traditions in general. The Golden Chain of Homer is an excellent example but I believe that all you will find online of it are truncated bastardized versions. The Rosicrucians generated a great deal of hermetic literature, but the philosophy goes back further than that if you start looking at the alchemical classics.
The second point, although you could say that hermetics and chaos are related, it's not saying very much. Hermetics is a natural philosophy, chaos is a state or condition of matter, and that is the traditional view. Matter can apply to very many things, including thought... The philosophy of hermetics did a lot to explain and popularise the idea of chaos, but not just chaos, of the whole structure of nature, inner and outer. Chaos is just one phase of matter, and while a neccesary one, it's definately not the end but just the part of a larger circle. The reason chaos can be a desirable condition is because it is the point where the boundaries between the elements are removed and the elements can then be accessed and separated for further purification.
A third point, the practice of hermetics. In the past hermetics was closely associated to lab alchemy, because one of the wonderful things about hermetism was that every point could be proven. Not just by argument or discussion, but by work that an individual could do. This work was on physical matter because it surrounds us, all of it contains everything that there is including spirit, soul, and body, and because work on a tangible substance can give a tangible experience which becomes knowledge, as opposed to just information, which is the best I think anyone can hope for by just reading, thinking, and discussing these ideas. The other point about working with the physical is that as a tangible substance, it can be shown to another, results can be compared, etc...

Hope that's helpful...
