Is Obeah evil?
Obeah itself is neutral. The person practicing it can be basically good or basically evil. No human is totally good, so it can be used for evil purposes.
One should ask themselves though, if a tiger is evil when she kills her prey or defends her cubs? Is a snake evil when he strikes because he is being threatened or mishandled?
Some people are specialists at doing works that cause death and destruction. They are not given this talent for no reason or somehow against Nature. Nothing can happen that Olodumare (a.k.a. YHWH or Elohim by the Jewish people) and Nature do not allow. They were given their abilities for the same reason snakes are born with fangs and tigers are born with claws.
How can I protect myself from Obeah curses?
Don’t do bad things to people. That’s it. Anyone, no matter how small or insignificant you may think they are, can enlist the help of an Obeah person. In fact, one of the ways it arose in the islands is to take revenge on slave owners and other exploiters.
When you do bad things to people, you put a wound on your soul. Even in the scientific sense, harming others damages you psychologically. So the more wrong you do to others, the more vulnerable you become to destructive forces of Nature.
Also, bear in mind that what Nature and the Spirits of Nature considers wrong may not be limited to what humans consider wrong. If, for instance, you marry someone for money or for the purpose of exploiting them, what you’re doing may be legal, but this does not make it right. If you are a police officer and you arrest someone for smoking marijuana and beat him, again, legal but not right. If this person or someone else on their behalf, takes the matter to an Obeah person, then you could be in trouble.
A curse is basically a removal of that person’s implicit protection over you in the natural network of humanity, and an entreaty to the Spirits for justice. Though you may not see it, all living beings and all things are connected. If that person’s wishing you well was the thing that stood between you and some disaster, you and perhaps those close to you will suffer.
By the same, most Obeah people will not throw a curse unless it is justified. Some however, are young and immature, but very talented and much like the seemingly random snake in the bush or malaria causing mosquito in the jungle. Some are just crazy or petty. Dangerous people exist to keep us from becoming lazy and overly compliant. However, if you don’t harm people on purpose, and try to make amends for your misdeeds, you will at least have some protection.
What do I do if I have been cursed?
Think back on all the wrongs you have done to people, and start making amends. It may be that nobody has actually cursed you, but that you have done so much dirt that you’re choking on it. Time to pay the piper.
If for some reason (such as causing greater suffering, or the person you wronged is dead) you cannot make amends, then you’ll need to take it up with the Spirits. You may have to compensate the person’s surviving family, peers, or descendants, or do certain actions or give offerings to the Spirits you offended to remove the curse.
Sometimes though, there is no way out. If you have been blessed, or got help from the Spirits to get something good, and then squandered or misused your gifts, you may never get them back. If, for instance, you were given the gift of beauty beyond your years by Oshun and then used that to exploit others, and someone throws a curse on you that this gift be taken away, you may not get it back, even if they forgive you. It’s Nature.
If you do your best to make up for your wrongs though, you will be blessed in other ways. You will at least have peace and be stronger for what you have learned.
