Ley Line

You can check out the Wikipedia entry for it for some of the history of the term in Western usage. Click Here: But I don't think it does justice to the term. It is a common enough concept in many eastern and far eastern and aboriginal belief systems to just go on what the writers in Wikipedia say. Additionally like a lot of things; there is a lot of different opinions out there on the term. I'll go into them at some point in the future.

Not only that it is used quite a bit in fiction and that also tends to have an influence on what people think.

Briefly,

I've read where people think some of the following:

- They are the connection points to overlapping dimensions in the multiverse as explained in quantium physics.

- Where two or more connections exist, vortexes occur. Gateways between the dimensions. Used by spritiual and ET entities.

- They could be like the nervous system of the planet. Channels or pathways for certain types of planetary or cosmic energy.

- They could be channels, pathways, or rivers of energy radiating from some divine source.

- They are often associated with psi, the paranormal, the various occult references or even religions
