This world is not made up of superstitions and bad omens.
That would mean that there would be something inherently evil in this world and evil does not exist. Nothing in this world is set up to harm you. There is however human free will, which is not set up to harm you, but that choice to choose love or hate is always there. That choice to feel victim-hood or empowerment is always there.
Superstitions were invoked to set up fear in others. To set up power and control dynamics. They also take personal responsibility seemingly out of the equation.
But know that you are ultimately responsible for your every action, for your every thought, for yourself. You have the free will to choose empowerment at every turn in the road.
