I have read various different interpretations of how our energies may benefit the world; from football fanatacism to war... in this article - called 'Trance Dancing - The Rave' - the author examines rave dancing as a means to supply vital energies. The author here takes a Gurdjieffian approach - i.e. ideas supplied by the Greek-Armenian mystic philosopher George I. Gurdjieff.
I quote an extract that focuses on a notion I particularly like, that of reciprocal maintenance:
Gurdjieff's answer fits into what he called "the doctrine of reciprocal maintenance", the idea that every thing exists only insofar as it supports or "feeds" something else. Everything is part of a vast, interconnected and mutually reinforcing web of life. Or, "everything is something else's lunch," as ecologists like to say. This idea anticipated the science of ecology by at least half a century.
Examples: Bees don't just exist for themselves, they live to pollinate flowers. Algae exists to turn sunlight into more complex molecules, and feed other small creatures, such as plankton and krill. Krill feeds other slightly larger creatures, and even whales. Plants exist to turn sunlight and raw matter into organic compounds, and to feed animals. Worms exist to loosen soil for plants. Bacteria recycle waste into useable raw matter. Predators help to increase the strength and fitness of the herds they prey on by eliminating the weak and sick. Etc. etc.
In the scheme of things, humanity's essential role is that of a transformer of energy.
Human beings, according to this view, exist to serve the cosmic evolutionary process--and not the opposite, as the Bible would have it: that all of creation is merely a resource for us to use and abuse as we see fit.
Our possibilities as human beings are dependent on the degree to which we fulfil this function, a kind of "obligation" which nature imposes on us.
By Gurdjieff's view, this special energy could be produced two different ways: either involuntarily, at the moment of death, when a small "packet" is released into the atmosphere, or voluntarily, in greater or lesser amounts, through spiritual work.
Since Mother Nature, or Gaia, needs a definite quota of this energy from us, she will do whatever is necessary to make sure she gets it. If we don't provide the required intensities while alive, the total number of deaths will have to be increased in such a proportion as to yield the needed amount."
The article is worth a read... after all, I'd rather choose the conscious 'alive' way of supplying energy, not the involuntary 'packet of energy' supplied on death...
