I would like to draw your attention to this article, it is very important to understand what is being said here. People, do not understand what is at stake. After reading this please do some research for yourselves. This is not a subject to take lightly, if you pardon the pun.
Gold light yourself and your home. You may also wish to gold light your work place too, you do not need to be physically present in the place that you gold light . It can be done remotely, I do this often. It is the intention that makes it work. White sage smudge sticks are also a very good work tool in clearing energy too and can be purchased on line or in a shop that sells metaphysical goods or even in a health food shop.
You may wish to ground and attune yourself too to keep yourself safe and strengthen your aura also.
You can find these exercises on my blog. Please do not try to do house clearances of energy clearing of people unless you are properly trained, as it can be quite dangerous. I have seen the results of poorly done clearances and I have had to fix the damage. It is irresponsible to do this without the proper training.
