*This is just a post to talk about the aggressive side of crystals since it is often forgotten and not talked about. I think it's so important to talk about all aspects of a popular tool used in the craft to make people more aware of ways to use it. Not everyone is okay with the idea of using a tool in an aggressive way cursing, hexing, etc. Which is totally understandable please do not judge someone else for their beliefs. And the debating on whether or not cursing, hexing, etc is ethical depends on personal beliefs.*
Crystals, probably one of the most used tools in the craft used commonly in a positive way such as protection, healing, spell-casting, etc, However, just because something is used in a positive aspect doesn't mean it can't be used in an aggressive aspect. Even using crystals in hex bags, spells, hex jars, etc. Can increase and have more of an impact. Hence, why I think incorporating a crystal in an aggressive way is such a powerful thing to do. Not only that but learning that crystals can be used in an aggressive way is so important to know because it only expands your knowledge on the tool and makes you more aware of the use of crystal. And why it's so important to cleanse your crystals when you buy them because you never know what type of energy is within the crystal good or bad you should still cleanse it. But also because over-time crystals do pick up energies good and bad even within your home which is also why its good to cleanse them, daily.
How do you use to charge them in an aggressive way?
Many people have different techniques and some people don't even use techniques they just use them as energy amplifiers in their spells, jars, bags, etc, However, one of the most commonly used technique is to charge your crystal which is something a lot of us know to do. You charge them with the unwanted emotions you have you are releasing that emotion and putting it into a crystal. Anxiety, depression, sadness, anger, all that unwanted emotions and storing it in a crystal and using it. Which can sound a bit scary but once you actually do it, it's not as scary, I promise!
How do I use the charged crystal?
Well, this is a question with many answers. How would you use a normal crystal in general in a spell, grid, bag, jar even? That's how you would use the charged crystal. If you are using a jar to hex a person put the crystal in the jar same goes with a bag. Though is it recommend to use crystal chips when working with jars and bags. Some might even give the person that charged crystal in hopes of that crystal causing bad luck on the person. But honestly, negative crystals are mostly used to add more of an impact or kick to the spell and to increase it working. Crystals are very powerful tools and I suggest doing further research on the different types of crystals before using just anyone.
Cleansing/Deactivating Crystals:
In my experience doing a simple cleansing of an aggressive crystal used isn't as simple as cleansing a normal crystal. I personally bury mine in the earth or cleanse mine with my Tibetan Singing Bowl or cleansed it with the fires smoke or the flames itself.
