Xevioso is the god or lord of thunder. A god of thunder is one of the most common in cultures around the world. In Yoruba’s version, he is considered the strongest. He represents wrath, aggression, and punishment. In other words, Xevioso is understood as primarily a spirit of explosive, uncontrollable emotion like anger, violence, and tremendous power. This is a double-edged sword as he can protect those who honor him, but if they offend him in any way, he will likely turn on them.
This is the spirit you turn to when you are looking for justice. Still, anger is usually a sign that something isn’t as it should be, or there has been a violation of some agreement or law.
In most cases, spirits host and govern over the earth, and there is a set of agreements we have towards one another: a type of an unspoken agreement. We go into the world having agreed on a particular set of rules like not stealing from or hurting each other, and so forth. And when someone steals from us, we feel violated, and we have a right to be angry about it, even more so if we know they are getting away with it. Your anger is a sign that someone is not playing by the rules, an injustice has been done. Given this, it is not illogical to suggest that exercising your anger would restore justice and, therefore, balance the world. In other words, Xevioso is the protector and dispenser of justice. Through his acts, he enforces and keeps relations between the gods in check and us. It is not senseless, aimless, unexplainable anger, or fury. Although we may not understand it sometimes, it adds up on a cosmic scale.
