This is a really polemic topic,even among occultists,but I might as well share my understanding about this.
Karma,or the Thrice returning law,I suppose.I can´t accept that there´s an all benevolent entity who will punish misdeeds or an elastic-like energy that will come back to hunt you for the shits you´ve done.In a world with pimps,bureaucreats and all kinds of nasty folks who keep running their business,this don´t make a lot of sense.
Also,we do live in an infinite universe,so it doesn´t make sense for this stuff to just go back to us.
So,what is then,this mysterious effect that many important and powerful occultists mention?
Well,I do believe that it´s related to action and reaction.Everything we do,has a consequence,may we like it or not.
Examples:Forgeting to wear the condom that one time may fuck you up,getting into a fight with the son of the principal at school will surely get you into trouble,although the negative consequences may take time to manifest,they will.
As practicing occultists,we are aware,and constantly deal with more potent forces and energies than most people,that´s why the rituals for protection and license to leave are so important.We become small magnets and lamps as we build our power.As a side effect,most of the time our actions are more intense.
This is the reason why it´s so important to divine the consequences of your ritual.
So it less about a metaphysical judge going at you with a really thick role and more about Newton´s stuff.
Make sure the person you are going to use a love spell on isn´t secretly a crazy psychopath
Search about how the disappearence of the person you are trying to curse will affect you
And ask yourself,is this person really worthy of the energy I will spend on a curse?
Thanks for the reading.
