What does the light evil spirit mean?

light evil spirit is a term in geomantic omen, which means that strong light has a serious adverse effect on the aura. The lighting in the home is second. Many high-rise buildings in modern cities are glass curtain walls, which look very imposing. However, from the perspective of geomantic omen, a large area of glass curtain walls or glass roofs will produce strong reflections, which will have a serious adverse effect on the surrounding buildings. We must pay attention to this problem when choosing houses, shops and office buildings.
