Humans have been studying energy for thousands of years- From the American Indians who knew all about the burning of herbs to cleanse negativity to the Ayurvedic medicine of the early Hindu cultures. Even the ancient Greeks and Romans had their energy studies.
Energy healing is based in scientific principles- weather you are discussing the fact all matter is made up of molecules and the vibration of each or getting into facts about positive and negative ions, there is a scientific backing to all that energetic principles we use.
All spaces can benefit from an energetic cleansing- Did you know that all electronics from TV's to cell phones and computers put off what is called positive ions. These ions begin to build up in a space and over time can cause a stagnant feeling. Also spaces hold on to energy imprints of things that happen there. When there is illness, death, family disruption, or other negativity that happens in a space there is a lingering energy that is left behind. If you fail to remove this negativity then like attracts like and more negative energy will be attracted there .
A space can be set up to attract the life you wish to build- After a home or office has been cleansed of any negative or existing energy, it needs to be filled with positive in order to prevent old from returning. When you do this, as you set your intentions for the space, you can program this area to attract the desires energy or manifestations.
Energy maintenance will serve you well- Weather it's physical or spacial it is always good to do some maintenance to keep the vibes as high as possible. At the end of the day a salt bath can help wash away negative things sticking to you or burn your favorite incense to help lift ther vibes of your space.
