There is no negative energy like people imagine in the house or body in the first place

There is no negative energy like people imagine in the house or body in the first place. It just is an irrational belief.

There can be psychological negativity because of toxic people around you and their behaviour, fears you get associated with a place or house (2), and negative thinking. You have to develop mental strength and rational thinking to deal with these things and to get rid of your fears.

If your health is not good, take the help of genuine qualified medical doctors.

Negative energy is a concept used in physics to explain the nature of certain fields. These are some examples ….

The positive gravitational attraction between two massive objects is accompanied by a negative amount of gravitational potential in the field which attracts them (1).

In quantum theory, the uncertainty principle allows the vacuum of space to be filled with virtual particle-antiparticle pairs which appear spontaneously and exist for only a short time before, typically, annihilating themselves again. Some of these virtual particles can have negative energy (1).

So if you have irrational beliefs, first get rid of them to remove unwanted outcomes in your life.

If you are surrounded by people who cause pain, either deal with them with mental strength or move away from them if you can’t deal with them.

Fears related with a house or people are again irrational. Develop rationality, scientific and critical thinking (3,4,5) to deal with them.

If you still can’t deal with them yourself, consult a genuine professional psychiatrist who could really help you.

Just taking a bath, using a ‘cleanser’ will not deal with any of these things and accepting advices from cheaters and fraudsters will cause more harm to you.
