Some science behind the scenes

Sacred geography - black streams

A black stream is a telluric current, or a collection of telluric currents whose influence is ‘black’, negative.  They may promote aggression, cause ill-health and malaise or reduce the fertility of the soil.  They are sometimes created accidentally by ill-informed land management or the removal of stones that played a key part in ancient times at keeping the currents ‘sweet’.

The View over Atlantic – John Michell

.... These upright stones were essential to the great work of alchemy which formed the climax of all prehistoric ritual, the introduction of solar or atmospheric energy into-the terrestrial life current……. Those who are now engaged in rediscovering the secrets of natural healing have noticed a connection between the incidence of such diseases as cancer and the location of houses placed above lines of earth current which have become sour, known as black streams. It has been found possible to purify these streams by driving metal stakes into the earth above their course. This has the effect of letting the atmospheric forces enter the flow of the earth current. Exactly the same principle forms the basis of Chinese medicine and acupuncture.

and from a site which deals with leys.....

When a ley line passes through decaying matter, like a burial-ground, dirty river or canal, the energy changes to a “black stream”..  ..Apart from this, underground streams, geological fissures and fault lines, coal mines, quarries, electric power stations and sub-stations, microwave towers, repeater television aerials, nuclear submarines and missile sites, etc., all alter the natural energies around them, adding to the massive geopathic stress which our modern world now suffers...........    owls, snakes, slugs and snails are attracted to black streams, ..... Insects, parasites, bacteria and viruses also thrive on black streams, and ant and wasps nests invariably provide a similar clue.

which is drifting into the realms of judgemental superstition, but interesting nonetheless.

'Black streams' are discussed at some length in the book 'Needles of Stone - revisited', by Tom Graves
