For protection and correct results, every dowsing session was preceded by meditation and a specific set of spiritual practices. Do not attempt to dowse a city without a deep practice in meditation and years of dowsing work in the field. Water lines are underground streams of water flowing through creaks and veins beneath the Earth's surface. Both ley lines and water lines create a field of energy that has an effect on onsciousness and how you feel. Once you teach yourself to be sensitive to Earth energies, you can feel their effect on you just like you feel the effect of a strong cup of coffee.
Power centers are places where ley lines begin.
A power center is created by the presence of both ley energy and underground water. The combination of the two creates a power that has the capability to not only affect consciousness, but also to retain the feelings of people who have visited the site. Power centers can save feelings and emotions in the same way a computer disk holds programs or a battery holds energy. More information on Earth energies. The easiest way to find ley lines and power centers is by dowsing.
