When you engage with Serpentine spirits, you'll find that not all of them are genuine or forthright, as serpents can indeed be rather selfish and self-interested at times. The good ones seek to shelter Vishnu from the storm, but the harmful variety are often more inclined to lie, mislead, and utilize emotionally-manipulative tactics to get their way. When you encounter people like this in your day to day life, it is helpful to have a firm grounding & a willingness to handle the trouble at hand. You will gain nothing from interacting with these individuals, and they are not worth the effort, the time, or the benefits they request.
They are full of venom, and if their words seem to spark more hatred and disdain without a focus on growth or beneficial change, see them as serpents and respond appropriately. Distance yourself from them and make a point of ensuring that they know it.
Then, its time to invoke Andromalius, for he has substantial wit and superb skills that render him a phenomenally potent demonic force and serpentine spirit with the capability of rendering these people powerless. He has a keen sense and eyesight aplenty to be well-able to see a venomous snake in the grass. Approach him with the sigil below & make offerings of milk, snake root, and poke root to invoke his aid towards this end.
This is only ever to be used if you are absolutely certain that this person is a venomous being, as if you call Andromalius incorrectly and in the wrong instance, he will not be happy about you wasting his time. If that occurs, offerings and payment will need to be made for that invocation, and you will need to make a point of digging deep to understand the cause of your incorrect assertion.
This is double-sided, double-edged magic. Use it carefully.
