Leys may be defined as lines of energy running over-ground in straight lines, often reflected in the paths of ancient trackways and subsequently Roman roads, and in alignments of prehistoric and historic sacred sites in the landscape. In modern times they were first described by Alfred Watkins in his 1925 book ‘The Old Straight Track’.

They carry Yang Qi relative to the Yin Qi of underground water and can be compared and contrasted with the more yin underground water lines as a yang energy matrix associated with a more heavenly consciousness. They are frequently worked by human ceremonial practice at sacred sites designed and constructed at key points in the landscape along these lines.

Perhaps the most famous Ley in Britain is the ‘Michael and Mary’ line, which runs across England from Hopton in Norfolk to St. Michael’s Mount in Cornwall.

Twin underground telluric currents, known as the Michael and Mary lines after the number of churches dedicated to either Mary or St. Michael to be found along them, weave around the central overground mid-line. This reveals the primal ‘Caduceus’ pattern that can be found within all true Leys: a triple-fold axis composed of masculine, feminine, and spirit currents, which may be experienced by the practising Geomancer as containing information in the thinking, feeling and spirit realms respectively.

Ley Lines are home to some of the most sacred temples and monuments in the world including the Egyptian Pyramids, Machu Picchu, Stonehenge and Angkor Wat.

Our Ancestors were very aware, and very connected, to these Earth Energies, imbuing them with their Sacred Intentions and Rituals.

There are many more sources and resources on Leylines and Earth Energies, also know as Geomancy and Dowsing.

Rory Duff in the UK has dedicated much effort to define and develop a modern lexicon for them in his Guidebook.
