The temple builders

So many of us in life start out building temples: temples of character, temples of justice, temples of peace. And so often we don’t finish them. Because life is like Schubert’s "Unfinished Symphony." At so many points we start, we try, we set out to build our various temples. And I guess one of the great agonies of life is that we are constantly trying to finish that which is unfinishable.
                             - Martin Luther King, 3 March 1968

One fact of life is that we can't fulfill all of our dreams. We have only limited time and resources. But modern life has a major additional obstacle which makes building temples more difficult than it needs to be--government. In particular, government's confiscation of resources which you might choose to use for your own benefit.

Bali is full of temples. Not only are there large public temples and town temples, but every home has a temple as well.

The family temples start off simple, using blocks cut and fabricated on a mass scale from sandstone or lava. The temples are nevertheless ornate as the blocs are combined in an exceptionally creative manner, and decorated with intricate finials. As the family becomes wealthier, they will add more finials to the gate, and the temples themselves, as well as add more (pagodas), decorate them with finials of stone or metal. It is clear that a significant portion of the family's capital and time have gone into them. Temples are key focal points for the family, and the village.

Lest you feel superior for not succumbing to superstition, I should remind you (as a North American or European) also devote a large portion of your income to the building of temples. However, these temples are not in your backyard, nor do you have much input into them. Instead, your income is diverted, often before you see it, towards temples built supposedly on your behalf by your elected representatives. Examples follow:

Did you ask for these? Did you want them built? Would you have built a different temple with your resources had they not been taken from you? Did building them fill you with serenity?

Have you seen the upkeep on them (especially the first two examples)? At least when you build a temple in your backyard, if you can't afford the maintenance, you can let it fall apart. What happens next is between you and God. But you aren't given the choice to let the Pentagon fall apart.

It's already hard to build the temples you want to build. Building a bunch of temples you don't want makes it harder.

Sunrise in Bali

Sometime ago we had a brief article on the geological hazards of calderas. Today we visit one--Mt. Batur, a live volcano within a pair of roughly concentric calderas.

The inner caldera represents a major blast that happened about 25,000 years ago, leaving a crater about 7.5 km across.


Google maps view of Mt. Batur, Bali.

Remember that as big as the caldera is, it doesn't represent the mouth of some supervolcano. It is a violent eruption that quickly empties a large magma chamber underground, the roof of which collapses into the chamber afterwards. So the size of the caldera reflects the approximate size of the magma chamber, not the mouth of the erupting volcano.


View from southwestern rim of the larger caldera. Much of 
the rim of the inner caldera is visible in the photo.

The blot above the left crater is on the inside of my dimestore camera.
The black area in the foreground is a recent (1968) lava flow.

Starting very early this morning (or very late last night) I climbed this to watch the sunrise over a small volcano on the edge of the caldera crater.

When I got off the plane on Tuesday, the first thing I saw was Indonesian news on the airport TV. I don't speak the language, but the all-caps NEWMONT and the disapproving looks of the commentators told me something was up.

Unfortunately, the Balinese don't know much about it (it is elsewhere in Indonesia), except to opine that people are unhappy with Newmont. And Newmont has issued no press releases this year, so it is unclear whether this is due to some new event or is simply ongoing discontent (perhaps this, for instance).
