Home environment is important. It creates an energy all of its own, and living in a "negative" nest creates a unhappy environment from which to function. Study friends of yours that tend to hoard and create a messy environment. Usually these people are in a state of fear, and actually it is nothing about the house. The extreme example is not what I care to address, but it may show up in a later post. However, it is the subtle environment. The one that you do not care to enter because it is a sad place to be. The Chinese call this Feng Shui. I just accept energy.
Often violence from the past could be a factor with energy. Years ago, my son and I went to a hamburger house in Atlanta for a sandwich. While there, for no reason, I was getting angry. The sandwich was good, but I left angry without knowing why. Remember, I am sensitive to feelings, and often are not aware myself. We arrived at our destination that night and I mentioned to my teacher how angry I had become over nothing. Two days later, she called and informed me that a murder had taken place in that restaurant. And from that point on the businesses that came into the space could not be successful. Her reason, the energy from the death scene was violent and the energy needed to be cleared. I did not need to be convinced. Families that tend to argue all of the time create a negative energy. More subtle, but it remains. Rather be safe than sorry. When moving into a new space always clear the energy.
To establish a healthy energy for a new residence or business, you can use prayer, candles, create your own holy water, or salt, and herbs. There may be more information on this subject, but my suggestion is to find your own path for cleansing. For me, I always bless every room. Ask God to bless the house with love and joy, and sprinkle a little holy water in each corner of the room as negative energy always attracts to the corners. Whatever the "ritual" is that you develop in the cleansing of a property, continue to use the exact ritual with other properties.
A point of observations here. Cultures are different. The Asian population regards red as good luck. We often use red in conjunction with anger. Asian uses crosses to mean death and destruction. Our Christian populations uses the cross as a Christian symbol yes it is death, but over change and redemption, not that of war. I've witnessed with amusement western man re-create feng shui as if he were a direct descendant to the Emperor of China himself. Groups incorporate their beliefs or superstitions to the point of creating a false "truth". If you believe that walking under a ladder, for example, is bad luck then guess what? You have created a superstition with a truth behind it. It is not so, but the group believes it and therefore it becomes bad luck. Many of the superstitions were created by different cultural groups. Be careful. My point, create a happy environment with prayer, plants, good room arrangement, candles, and cleanliness, and you will change the energy all by your lonesome self.
