In some spiritual traditions, there are spirits known as hot spirits. I will not overshare religious secrets of foreign faiths, but what this means is that once they are attached to you, they feel as if they are angry spirits and they typically have a strong energy. Many people actually think they’ve been cursed once they get one of these because it is very intense and powerful. This energy can be overwhelming just coming from yourself, let alone deities.
Keeping that in mind, it makes sense once we consider your soul flame feels very similar to anger besides the negative energy component. Anger is hot energy with an emotional component of irritation. This means that all anger has a component of hot energy. Hot energy can easily become anger when exposed to mistreatment or topics such as news. Many revolutionaries or people who end up chronically angry are like that because they have so much hot energy coming from their soul flame and end up being out of control of it. Before you get riled up, go ahead and send all of this energy towards manifesting or improving yourself in some way. Even meditating and allowing your soul flame to flow freely through your aura and entire body is a good way to harness it.
Keep in mind as well that hot energy should not be played with. A lot of toxic people or those who seek arguments and conflict do so because they have a soul flame that builds up a ton of energy. They then go out into the world to argue, which on the energetic level causes their soul flame to burn others because oftentimes an argument or rude remark is an energetic attack on another person. But when you’re engaging in this behavior, you can possibly burn yourself with your own flame, so it’s not recommended at all to go and use your soul flame for such destructive and counterproductive purposes when that energy can more easily be sent towards things that you desire and enjoy.
