The Sacred Network by Chris H. Hardy, PhD, argues that ancient megaliths and modern cathedrals are built upon a global grid of earth energies (ley lines) that act as antennae for cosmic energy, fostering higher consciousness. Hardy demonstrates how these sites create a shared, elevated consciousness, specifically tracing a profound network of sacred sites in Paris. Hardy combines scientific concepts with spirituality, suggesting that the "Sacred Network" is both a physically tangible network of,sites and a powerful, energetic, and invisible web of consciousness.
