There are numerous techniques to determine if there is negative energy in your home. The simplest way to do this is by using a glass filled with water.
What in the first place is negative energy?
Each of us has our own energy that stays in the places where we stay and in the objects we use. Our homes are places where different energies are encountered, both from ourselves and from family members. Every person who enters our home also brings in a certain type of energy, and it can be positive or negative. Negative energy causes stress, health and financial problems and bad feelings. If you think that such energy is present in your home, take immediate action.
Put sea salt in clear glass (about 1/3 of the glass). After salt, pour 1/3 of cold water and 1/3 of white vinegar in the glass.
Put the glass in the room where you think negative energy is present.
After you have put the glass there, no one should touch it for the next 24 hours. If the liquid in the glass is in the same condition as you left it in, you can relax, there is no negative energy in that room. But if you notice bubbles in the glass or the liquid becomes opaque, it's obvious that you have some problems. After the liquid in the glass has absorbed negative energy, throw the liquid in the toilet and flush the water. Repeat the procedure every day until the liquid in the glass becomes clear.
