We should note that all of these places of thermal extremes (Finnish saunas, Japanese hot baths, American beaches and mountains) have their opposites close at hand. There are possibly two reasons for having the extremes right next to each other.
The first is physiological: the availability of extremes ensures that we can move from one to the other to maintain a thermal balance.
The second might be termed aesthetic: the experience of each extreme is made more acute by contrast to the other.
Works of art which have great life often have intense contrast within: rough/smooth, solid/void, loud/silent, empty/full. It is the difference between opposites which gives birth to something. Contrast is what often gives other principles their degree of life – the intensity of the boundary, the markedness of the alternating repetition.
Contrast strengthens centers by making each a deeper entity of itself, and thereby giving deeper meaning to both. It is, at its simplest, what allows us to differentiate. But meaningless contrast remains meaningless. It is only when centers are actively, mutually, and meaningfully composed that it acts to deepen the whole.
Applied to a blog, angkorwatification is a sort of textual equivalent of rewilding. You have a base layer of traditional blog posts that is essentially complete in the sense of having created, over time, an idea space with a clear identity, and a more or less deliberately conceived architecture to it. And you have a secondary organic growth layer that is patiently but relentlessly rewilding the first, inorganic one. That second layer also emerges from the mind of the blogger of course, but does so via surrender to brain entropy rather than via writerly intentions disciplining the flow of words.
