Water is the element of the Northeast.
The Northeast must always be lower and more open than the Southwest. Depressions such as built in pools, ponds, valleys or wells should not be placed in the negative field as any hole or depression will increase the energy potential of a field. To create a depression in the South or Southwest is to invite death and misery into the site. The natural flow of energy is disrupted and it can be likened to the backing up of a septic system, bringing untold suffering to the inhabitants. When the Northeast is lower and more open than the Southwest, the site becomes very rich in energy and the inhabitants experience great blessings.
