This is a spell I just used so I know it works. :3 It's also one that I made. Use this to draw out any negative energies and emotions that are building in you. It's very simple and you do not need much.
Ingredients:
A cup (any)
Water
Cast a circle around yourself and fill a cup full of water. Note the weight. Now hold your hands over the cup and channel all of the negative emotions. Anything that does not allow you feel light, you should channel into the water not the cup. While channeling all of the negativity into the water chant:
That which keeps me from my best
I will now lay you to rest.
Chant this as many times as you feel necessary and keep channeling those energies and emotions until you are satisfied. After this is done, go outside so you can pour the water out into the ground. Your cup should also feel heavier than it started. As you pour, chant:
No longer darken on my hearth
I now return you to the earth
And Ta-da! You should feel lighter. I did. I would imagine that this could be modified for purifying areas but I haven't tried that yet so, I'll have to get back to you on that. =) I hope this helps some people!
* Edit
I have tried using this technique on pulling out negative energy from a room. I'm not that skilled yet at this kind of thing so it didn't help a lot but it did provide some help. :3 What I did:
I kept the water and all of the instructions above. However I grounded myself and I used the element that responded to me. Normally I get Emerald Fire but since Ra has made contact with me, Blue fire has been showing itself. Anyways, I used that flame to herd and guide the negative energy hanging around my room and pushed it into the water, while keeping the same chant.
I was pretty tired when I did this so I know it wasn't extremely effective but it did help a little bit. Like the alternative spell for removing negativity from yourself, this most likely can be modified with crystals or herbs or whatever method you choose! I hope this helps! =^_^=
